Functional Description
1. Basic
operation
The motor is driven by the square-wave turn-on signal based on a positional signal. When the positional
signal reaches number of rotations f = 5 Hz or higher, the rotor position is assumed according to the
positional signal and a modulation wave is generated. The modulation wave and the triangular wave are
compared then the sine-wave PWM signal is generated and the motor is driven.
From start to 5 Hz: When driven by square wave (120 turn-on) f = f
osc
/(2
12
32 6)
5 Hz~: When driven by sine-wave PWM (180 turn-on)
When f
osc
= 4 MHz, approx. 5 Hz
2. Function to stabilize bootstrap voltage
(1) When voltage instruction is input at V
e
<
= 0.2 V:
Turns on the lower transistor at regular (carrier) cycle. (On duty is approx. 8%)
(2) When voltage instruction is input at V
e
> 0.2 V:
During sine-wave drive, outputs drive signal as it is.
During square-wave drive, forcibly turns on the lower transistor at regular (carrier) cycle.
(On duty is approx. 8%)
Note: At startup, to charge the upper transistor gate power supply, turn the lower transistor on for a fixed
time with V
e
<
=
0.2 V.
3. Dead time function: upper/lower transistor output off-time
When driving the motor by sine-wave PWM, to prevent a short circuit caused by simultaneously turning
on upper and lower external power devices, digitally generates dead time in the IC.
When a square wave is generated in full duty cycle mode, the dead time function is turned on to prevent a
short circuit.

4. Correcting
lead
angle
The lead angle can be corrected in the turn-on signal range from 0 to 58 in relation to the induced
voltage.
Analog input from LA pin (0 V to 5 V divided by 32)
0 V = 0
5 V = 58 (when more than 5 V is input, 58)
5. Setting carrier frequency
Sets triangular wave cycle (carrier cycle) necessary for generating PWM signal.
(The triangular wave is used for forcibly turning on the lower transistor when driving the motor by
square wave.)
Carrier cycle = f

8. Protecting

pin
1.
Overcurrent protection (Pin I
dc
)
When the DC-link-current exceeds the internal reference voltage, performs gate block protection.
Overcurrent protection is released for each carrier frequency.
Reference voltage = 0.5 V (typ.)
2.
Gate block protection (Pin RES)
When the input signal level is Low, turns off the output; when High, restarts the output.
Detects abnormality externally and inputs the signal to the pin RES.

3. Internal
protection
Positional signal abnormality protection
When the positional signal is HHH or LLL, turns off the output; otherwise, restarts the output.
Low power supply voltage protection (V

monitor)
When power supply is on/off, prevents damage caused by short-circuiting power device by
keeping the turn-on signal output at high impedance outside the operating voltage range.

The modulation waveform is generated using Hall signals. Then, the modulation waveform is compared
with the triangular wave and a sine-wave PWM signal is generated.
The time (electrical degrees: 60) from the rising (or falling) edges of the three Hall signals to the next
falling (or rising) edges are counted. The counted time is used as the data for the next 60 phase of the
modulation waveform.
There are 32 items of data for the 60 phase of the modulation waveform. The time width of one data
item is 1/32 of the time width of the 60 phase of the previous modulation waveform. The modulation
waveform moves forward by the width.
In the above diagram, the modulation waveform (1)' data moves forward by the 1/32 time width of the
time (1) from HU: to HW: . Similarly, data (2)' moves forward by the 1/32 time width of the time (2) from
HW: to HV: .
If the next edge does not occur after the 32 data items end, the next 32 data items move forward by the
same time width until the next edge occurs.
The modulation wave is brought into phase with every zero-cross point of the Hall signal.
The modulation wave is reset in synchronization with the rising and falling edges of the Hall signal at
every 60 electrical degrees. Thus, when the Hall device is not placed at the correct position or when
accelerating/decelerating, the modulation waveform is not continuous at every reset.

To stabilize the bootstrap voltage, the lower outputs (X, Y, and Z) are always turned on at the carrier cycle
even during off time. At that time, the upper outputs (U, V, and W) are assigned dead time and turned off
at the timing when the lower outputs are turned on. (T

)

When the motor is driven by a square wave, acceleration/deceleration is determined by voltage V
e
. The
motor accelerates/decelerates according to the On duty of T
ONU
(see the diagram of output On duty on
page 11).
Note: At startup, the motor is driven by a square wave when the Hall signals are 5 Hz or lower (f
osc
=
4 MHz) and
the motor is rotating in the reverse direction as the TB6551F controls it (REV
=
High).

When the motor is driven by a sine wave, the motor is accelerated/decelerated according to the On duty of
T
ONU
when the amplitude of the modulation symbol changes by voltage V

(see the diagram of output On
duty on page 11).

Note: At startup, the motor is driven by a sine wave when the Hall signals are 5 Hz or higher (f

4 MHz) and the
motor is rotating in the same direction as the TB6551F controls it (REV
=
Low).
