1. Functional Diagram

2. Description

The MLX90805 is a power control IC ideally
suited for control of any resistive or inductive
load regulated by a triac.
The chip was designed primarily for starting and
speed control of AC motors, but will work equally
well with any Inductive or resistive load such as
Incandescent lights.
The chip's primary purpose is to provide a "soft
start" for a motor, preventing current inrush. The
triac is controlled by a linear "ramp" from
minimum to maximum power. Start rate can be
varied from 0.5 sec. to 3 sec, by changing the
option bits.
The secondary function of the MLX90805 is
proper ignition of the triac for inductive and
resistive loads, while keeping the triac's current
consumption to a minimum.
Added features include a frequency locked loop
for stable ignition point.

6. General Description

Voltage Regulator

The chip is supplied from the AC line voltage, by
a half wave rectifier. The voltage at pin VDDA is
limited to ~ 15.5V. The digital part and some of
the peripheral blocks are supplied by internally
generated VDD ~ 5V.

Analog Power on Reset

This block tracks the voltage at VDDA, and
permits generation of firing pulses for the triac
only if VDDA > ~13V. It is considered otherwise
that the motor is not properly supplied by the
mains.

Oscillator

There is an on chip oscillator. All timing
constraints inside the chip are derived from this
clock.

FLL

A frequency locked loop circuit is implemented
to obtain a clock frequency from a current
controlled oscillator, by using the mains
frequency as a reference. A successive
approximation algorithm is used at start up to
minimize the time for the oscillator adjustment.

Reference Voltage

This voltage is used to supply the external
potentiometer for the definition of different speed
settings.

ADC

The analog signal from the potentiometer, which
defines the speed setting, is transferred into
digital by a 4-bit ADC. The reference for the
converter is the voltage used to supply the
potentiometer.

ROM

The digital words from the ADC act as the
address of a ROM table in which the different
firing angles are programmed. This means that
16 different firing angles can be selected.

Zero Cross

This block detects the moments when mains

voltage crosses zero level. An accurate
detection allows good synchronization, so firing
pulses driving the triac can be generated at the
right moment.

Logic

This block performs all control functions to
realize time synchronization, smooth soft start,
and proper triac firing, so that motor runs at a
defined speed.

Triac Driver

This output is able to drive a triac through an
external resistor RT (typically RT is 150). It
defines the triac gate current and operates as a
switch.

Auto Retriggering

This block tracks if the triac is on after each firing
pulse. If the triac is off 20us after a firing pulse, a
new pulse is generated.

Thermal Protection

The chip is able to supply an external protection
circuitry, typically an NTC resistor with reference
resistor, to track the ambient temperature. If the
voltage at THP equals Vref/2 the protection is
activated and the chip sets the firing angle
defined by the value in ROM address 1. A
resistor connected to pin FB can introduce
hysteresis in the detection level.

Options

This block defines different modes of the chip
operation.

7. Digital Features

Debounce of ADC

The result from the potentiometer reading must not
jump from one position to the other, therefore a
special debouncing is designed. The debounce
circuit compares the current value from the ADC
with the previous one. The new value is accepted
only if the absolute difference between the new
and the previous value is greater then 1 LSB.

Power Settings (ROM table)

The ADC output data is applied after debouncing at
the address bus of the ROM and the corresponding
power settings are available at its data output
SETP[9:0]. The content of the ROM can be defined
freely: it does not need to be linearly or continuous.
When the potentiometer setting is changed from
one position to the other, the phase angle is moved
to the new position via the soft start procedure,
avoiding abrupt changes.
For programming the different speed settings in the
ROM table, following formula can be used, given ti
(in msec) is the delay from the previous zero
crossing to the moment of ignition:

]

[

Fmains

ROMi

f.e.: for a phase angle of 50%, ti = 5msec for a
50Hz mains, and thus:

490

]

[

ROMi

Note:
The value should not be negative: very small
values can not be programmed.

Soft Start

The soft start is initiated after the supply voltage
has been built up. This behavior guarantees a
gentle start-up for the motor and automatically
ensures the optimum run-up time. The motor is
fired initially with a very small phase angle, i.e. a
delay time very close to half the mains period. The
phase angle is than increasing up to the phase
angle defined by the potentiometer setting. The
rate of increase is defined by the option ATN[4:0].
This option defines the time to increase the phase
angle from minimum to maximum. If the phase
angle, selected by the potentiometer, is not the
maximum phase angle then the soft start run-up
time is decreased proportionally.

Firing

The soft start circuit generates a predefined set of
values for the ignition angle IGN. These values are

compared with the value of a down counter,
which is clocked by DCLK = 100kHz (the
resolution is 10 us) and is cleared at beginning of
every half period of mains. When the counter
value becomes equal to IGN the firing circuit
produces an ignition pulse GATE with duration
20us, 40us, 80us or 320us. This duration can be
chosen with option DUTS[1:0]. The retriggering
circuit checks whether the triac is ON, if not
additional firing pulses are generated every 20us
(with respect to the end of the previous firing
pulse) until firing of the triac.

Thermal Protection

An external circuitry supplied by VREF defines
the voltage at pin THP. This voltage is
proportional to Tamb. It is tracked by an internal
comparator referred to VREF/2. The tracking
process is sampled. When the switch is ON (see
block diagram), the chip checks if Tamb is
greater than a predefined value. If yes, the motor
is driven to operate at the speed defined at the
first ROM address. During the time when the
switch is OFF, the chip checks what kind of mode
is defined by the external elements: 2-wire or 3-
wire potentiometer connection. A reconnection of
the elements used for thermal protection is
needed only to define the active mode of
operation.

The temperature for which thermal protection
becomes active or not is defined by the external
elements, keeping in mind that comparator is
referred to VREF/2.
In the case when thermal protection is not used,
pin THP should be connected to pin FB, which is
connected either to Vss or to Vref, depending on
the mode.

2-wire mode, if V(FB) = VREF
3-wire mode, if V(FB) = VSS

Options

The following options are available:

Firing angle definition

The firing angles, and corresponding motor
speeds, can be defined in ROMi[9:0]. This is the
ROM table, which is addressed by the ADC
reading the potentiometer setting. The ROM
contains 16 words of 10 bits. For programming
the different speed settings in the ROM table,
following formula can be used, given ti (in msec)
is the delay from the previous zero crossing to
the moment of ignition:

Fmains

ROMi

With: Fmains = frequency of the mains (in Hz)
Note:
The value should not be negative: very small
values can not be programmed.
The content of the ROM can be defined freely: it
does not need to be linear or continuous. However
for a proper soft start generation under all
conditions, the value with minimum firing angle
(thus maximum speed) must be in the highest
ROM address.

Maximum phase angle

Independent of the phase angle definitions in the
ROM table, a maximum phase angle can be
defined. This is the phase angle that will be applied
immediately after the power on sequence, and is
therefore the first phase angle in the soft start
sequence.
This maximum phase angle is defined in MIN[9:0]
with the formula:

MIN[9:0] = Tini * 2 * Fmains - 10

With:

Tini

= the initial phase angle (in msec)

Fmains

= frequency of the mains (in Hz)

Default value:

Tini

= 7 msec and

Fmains

= 50Hz, thus MIN[9:0]

is 690.

Soft start time duration

There are 5 bits ATN[4:0] used to define the
duration of the soft start time. The bits can be
calculated with following formula:

Ts = ((Tini � Tmin) * ATTN * 800) / Fmains

With:

= the duration of the soft start (in msec.)

Tini

= the initial phase angle defined by MIN[9:0]

(in msec)

Tmin

= the phase angle corresponding to the

value in the highest ROM address (in msec).

ATTN = bin2dec(ATN[4:0]+1)

, a value

between 2 and 32.
Default value:

Tini

= 8msec,

Tmin

= 1.84 msec,

ATTN

= 32,

thus

= 3.15 sec.

Firing pulse duration

The duration of the firing pulses can be defined by
the bits DUTS[1:0] and is equal to

DUT/(1000 * Fmains).

The value of DUT is defined in the following table:

DUTS1 DUTS0 DUT
0 0 16
0 1 4
1 0 2
1 1 1

The default value is 20 usec (for Fmains = 50Hz).

Enable Retriggering

With bit RTRIG set to 1, triac retriggering is
enabled. The retriggering circuit checks whether
the triac is ON, if not additional firing pulses are
generated every 20us (with respect to the end of
the previous firing pulse) until firing of the triac.
With bit RTRIG set to 0, triac retriggering is
disabled. For each triac firing two pulses are
generated with a delay of 20 usec (with respect to
the end of the previous firing pulse).

The default value is triggering enabled.

Retriggering Mask

With the option MINA[3:0] it is possible to define
a zone at the end of each half cycle of the mains
voltage, where it is impossible to generate
retriggering pulses. This has two purposes:

With some (non-inductive) loads the current can
become quite small at the end of each half cycle.
This can eventually activate the retriggering
circuit, which will unnecessarily generate
additional pulses thus increasing the current
consumption.
When generating a retriggering pulse just before
the zero crossing, this pulse could overlap to the
next half period. With some (non-inductive) loads
this can lead to false triggering at full power and
must be avoided.
The bits MINA[3:0] are defined according to the
following formula:

Tmina * 2 * Fmains = MINA[3:0] * 64

With:

Tmina

= the phase angle from which retriggering

is prohibited (in msec)

Fmains

= frequency of the mains (in Hz)

Default value:
MINA[3:0] = 1101

(2)

= 13

(10)

and Fmain = 50Hz,

this means that retriggering is prohibited at
8.32ms.

9.2. Soft Start With 2-Wire Setting

The speed control is performed in addition to the
soft start in this application. A potentiometer in 2-
wire connection is used to define different speed
settings. An additional resistor RP with value
equal to the potentiometer is used to keep the
ADC input to be ratiometric. In this case, the
input signal for the ADC varies between 0 and
VREF/2.
The minimum speed corresponds to a
potentiometer set to its maximum value.
Maximum speed corresponds to a potentiometer
set to its minimum value (I.e. Rpot = 0). When
the mains voltage is applied to the system, the
motor starts running at a speed defined by the
potentiometer, as soon as the soft start time has
finished.

The disadvantage of the 2-wire application is
that, at minimum speed setting, the tolerance on
the absolute value of the potentiometer defines
the tolerance of the voltage at the SET input,
resulting in a less accurate selection of the
minimum speed setting. This can be avoided
when using the 3-wire application.
The voltage at SET is transferred to a 4-bit value
to address a ROM table in which the different
phase angles are defined with a 10-bit
resolution.
The 2-wire mode is selected by connecting VFB
to VREF (eventually via a resistor).
Note:
R1, R2 and NTC are only needed for thermal
protection, and can be left out otherwise

9.3. Soft Start With 3-Wire Setting

The speed control is performed in addition to the

The minimum speed corresponds to a maximum
voltage at SET. Maximum speed corresponds to
a minimum voltage at SET. When the mains
voltage is applied to the system, the motor starts
running at a speed defined by the potentiometer,
as soon as the soft start time has finished.
The voltage at SET is transferred to a 4-bit value
to address a ROM table in which the different
phase angles are defined with a 10-bit
resolution.
The 3-wire mode is selected by connecting VFB
to VSS (eventually via a resistor).
