Multiple voltage regulator
TDA3615J
FUNCTIONAL DESCRIPTION
The TDA3615J is a multiple voltage regulator intended to
supply a microprocessor (e.g. in car radio applications).
Because of low-voltage operation of the application,
a low-voltage drop regulator is used in the TDA3615J.
Regulator 1 (5 V standby) will switch on when the supply
voltage exceeds 7.2 V for the first time and will switch off
again when the output voltage of the regulator drops below
3.5 V.
Reset is used to indicate that the regulator output voltage
is within its voltage range. This start-up feature is built-in to
secure a smooth start-up of the microprocessor at first
connection, without uncontrolled switching of the standby
regulator during the start-up sequence.
All other regulators and switches can be switched on and
off by using the three control input pins. This is only
possible when both supply voltages (V
bat
and V
I(ig)
) are
within their voltage range. Table 1 shows all possible
states.
The filament regulator output voltage of the TDA3615J can
be adjusted with pin FILADJ.
All output pins are fully protected. The regulators are
protected against load dump and short-circuit (foldback
current protection, except the filament regulator output).
At load dump all regulator outputs will go LOW except the
5 V standby regulator output.
The antenna switch and the media switch can withstand
`loss of ground'. This means that the ground pin is
disconnected and the switch output is connected to ground
(V
bat
and V
I(ig)
are normally connected to the right pin).

4. The foldback current protection limits the dissipation power at short-circuit.
5. The drop-out voltage of regulators 2 to 6 and power switches 1, 2 and 3 are measured between V

or
between V

Noise figures
Note
1. Measured at a bandwidth of 1 MHz.
The regulator outputs for regulators 2 to 6 are designed in
such a way that the noise is very low and the stability is
very good. The noise output voltages are depending on
the output capacitors. Table 2 describes the influence of
the output capacitors on the output noise.
S
TABILITY
The regulators are made stable with the external
connected output capacitors.
With almost any output capacitor, stability can be
guaranteed; see Figs 5, 6 and 7.
When only an electrolytic capacitor is used, the
temperature behaviour of this output capacitor can cause
oscillations at extreme low temperature. The next
2 examples show how an output capacitor value is
selected. Oscillation problems can be avoided by adding a
47 nF capacitor in parallel with the electrolytic capacitor.
Example 1 (regulator 1)
Regulator 1 is made stable with an electrolytic output
capacitor of 10
F (ESR = 3.1
). At
-
30
C the capacitor
value is decreased to 3
F and the ESR is increased to
22
. The regulator will remain stable at
-
30
C; see Fig.5.
Example 2 (regulator 5)
Regulator 5 is made stable with a 2.2
F electrolytic
capacitor (ESR = 8
). At
-
30
C the capacitor value is
decreased to 0.8
F and the ESR is increased to 56
.
Using Fig.6, the regulator will be instable at
-
30
C.
Even when only a small MKT capacitor of 47 nF is used as
output capacitor, regulator 5 will remain stable over all
temperatures.

OSS OF GROUND PROTECTION
Two power switches (media and antenna) are protected
for loss of ground. The loss of ground situation is depicted
in Fig.8. The ground terminal of the battery is connected to
the output of the media switch. Two problems occur:
1. At first connection a high charge current will flow
through C1 to the ground terminal (pin 17) of the
TDA3615J and out of the switch output (pin 11).
The media and antenna switches are protected to limit
this current.
2. When the switch is enabled, a short-circuit current will
flow out of the power switch output (pin 11) because
the output of the switch is shortened below substrate
potential.
A special protection is built-in to avoid the media and
antenna switches from being damaged during a loss of
ground condition.
In practice, this condition can occur when the ground
terminal of the total application is connected to the switch
output due to a bad wiring.
C
APACITIVE LOADS ON POWER SWITCHES
Power switches can deliver a large current to the
connected loads. When a supply voltage ripple is applied,
large load currents will flow when capacitive loads are
used in parallel with normal loads.
When the output of a power switch is forced above V
I(ig)
an
internal protection is activated to switch off the switch as
long as the fault is present.
The display switch in particular is sensitive to capacitive
loads.
We therefore strongly advise:
Use only a 47 nF output capacitor on the display switch
Use a 10
F capacitor on the outputs of the antenna and
media switch.
On the outputs of regulators 2 to 6 a capacitor of 47 nF can
be used; larger values are possible but not necessary to
guarantee stability; see Figs 4, 6 and 7.

SOLDERING
Introduction to soldering through-hole mount
packages
This text gives a brief insight to wave, dip and manual
soldering. A more in-depth account of soldering ICs can be
found in our
"Data Handbook IC26; Integrated Circuit
Packages" (document order number 9398 652 90011).
Wave soldering is the preferred method for mounting of
through-hole mount IC packages on a printed-circuit
board.
Soldering by dipping or by solder wave
Driven by legislation and environmental forces the
worldwide use of lead-free solder pastes is increasing.
Typical dwell time of the leads in the wave ranges from
3 to 4 seconds at 250
C or 265
C, depending on solder
material applied, SnPb or Pb-free respectively.
The total contact time of successive solder waves must not
exceed 5 seconds.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T
stg(max)
). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
Manual soldering
Apply the soldering iron (24 V or less) to the lead(s) of the
package, either below the seating plane or not more than
2 mm above it. If the temperature of the soldering iron bit
is less than 300
C it may remain in contact for up to
10 seconds. If the bit temperature is between
300 and 400
C, contact may be up to 5 seconds.
Suitability of through-hole mount IC packages for dipping and wave soldering methods
Notes
1. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.
2. For PMFP packages hot bar soldering or manual soldering is suitable.
