TDA3606A
FUNCTIONAL DESCRIPTION
The TDA3606A is a 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 TDA3606A.
This regulator will switch on when the supply voltage
exceeds 7.6 V for the first time and will switch off again
when the output voltage of the regulator drops below
2.4 V. When the regulator is switched on, the RES1 and
RES2 outputs (RES2 can only be HIGH when RES1 is
HIGH) will go HIGH after a fixed delay time (fixed by an
external delay capacitor) to generate a reset to the
microprocessor.
RES1 will go HIGH by an internal pull-up resistor of 4.7 k
,
and is used to initialize the microprocessor. RES2 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 regulator during the
start-up sequence.
All output pins are fully protected. The regulator is
protected against load dump and short-circuit (foldback
current protection).
Interfacing with the microprocessor can be accomplished
by means of a battery Schmitt-trigger and output buffer
(simple full/semi on/off logic applications). The battery
output will go HIGH when the battery input voltage
exceeds the HIGH threshold level.
