GENERAL DESCRIPTION

The TDA3604Q and TDA3604TH are multiple output
voltage regulators with a power switch, intended for use in
car radios with or without a microcontroller.

It contains one fixed voltage regulator with a foldback
current protection (regulator 1) and one fixed voltage
regulator (regulator 2), intended to supply a
microcontroller, that also operates during load dump and
thermal shutdown.

There is a power switch with protections, operated by an
enable input.

The reset and ignition outputs can be used to interface by
the microcontroller. The reset signal can be used to call up
the microcontroller and the ignition output indicates
ignition voltage available.

Both supply pins can withstand load dump pulses and
negative supply voltages.

Regulator 2 will be switched on at a supply voltage >6.5 V
and off at a voltage of regulator 2 <1.9 V.

Philips Semiconductors Product specification

Multiple voltage regulators with external
reset delay and switch

TDA3604Q; TDA3604TH

FUNCTIONAL DESCRIPTION

The TDA3604Q and TDA3604TH are multiple output
voltage regulators with a power switch, intended for use in
car radios with or without a microcontroller. Because of
low-voltage operation of the car radio, low-voltage drop
regulators are used.

Regulator 2 will switch on when the supply voltage
exceeds 6.5 V for the first time and will switch off again
when the output voltage of regulator 2 drops below 1.9 V
(this is below an engine start). When regulator 2 is
switched on and the output voltage of this regulator is
within its voltage range, the reset output will be enabled
(reset will go HIGH via a pull-up resistor) to generate a
reset to the microcontroller. The reset cycles can be
extended by an external capacitor at C

RES

(pin of the reset
delay capacitor). The above mentioned start-up feature is
built-in to secure a smooth start-up of the microcontroller
at first connection, without uncontrolled switching of
regulator 2 during the start-up sequence.

When both regulator 2 and the supply voltage (V

P

> 4.5 V)
are available, regulator 1 and the power switch can be
operated by the enable inputs V

en(REG1)

and V

en(sw)

respectively.
All output pins are fully protected. The regulators are

protected against load dump (regulator 1 will switch off at
supply voltages higher than 25 V) and short-circuit
(foldback current protection).
The power switch contains a current protection which is
delayed for ≥10 ms (in short-circuit condition). During this
time the current is limited to 1.4 A (VP≤ 18 V).

At supply voltages over 16.9 V the power switch is
clamped at 15.0 V (to avoid externally connected circuitry
being damaged by an overvoltage) and the power switch
will switch off at load dump.

Interfacing with the microcontroller can be accomplished
by an ignition Schmitt trigger and ignition output buffer,
(simple full/semi on/off logic applications).

The total timing of a semi on/off logic set is shown in Fig.4.

Noise information

The noise at the output of the regulators depends on the
bandwidth of the regulators, which can be adjusted by the
output capacitors. Table 1 shows the noise figures.

Although stability is guaranteed when CL is higher than
10 µF (over temperature range) with tan (φ) = 1 in the
frequency range 1 to 10 kHz, however, for low noise, a
47 µF load capacitor is required.

The noise on the supply line depends on the value of the
supply capacitor and is caused by a current noise (output
noise of the regulators is translated into a current noise by
the output capacitors). When a high frequency capacitor of
220 nF with an electrolytic capacitor of 100 µF in parallel is
placed directly over V

P

and GND (pins of supply voltage

and ground) the noise is minimized.

SHORT CIRCUIT BEHAVIOUR OF POWER SWITCH

The short circuit behaviour of the switch with large
inductive loads (switch output goes out of the radio) can be
improved by replacing C2 (see Fig.7) by a larger
electrolytic capacitor of 10 µF/16 V. When the temperature
protection of the switch becomes active, due to a short
circuit of the switch, the behaviour will be improved.

When the switch is clamped an minimum output capacitor
of 10 µF is needed.

The power switch is not protected against ‘loss of ground’
condition (= short of the switch to ground with floating
ground pin of the TDA3604 itself). A ‘loss of ground’
situation can in practice only occur when the switch output
goes outside the car-radio box.

There is an application solution to protect against ‘loss of
ground’ (see Fig.8).

It is advisable to limit the dissipation at short circuit
condition by monitoring the output of the power switch.
The microprocessor can switch of the power switch when
the switch was enabled and the switch output remains low
due to a short circuit condition.

SOLDERING
Introduction

There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.

This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our

“IC Package Databook”

(order code 9398 652 90011).

DBS

SOLDERING BY DIPPING OR BY WA VE
The maximum permissible temperature of the solder is

260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. 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.

R

EPAIRING SOLDERED JOINTS

Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, 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.
