FUNCTIONAL DESCRIPTION
The TDA3616 (see Fig.1) 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.
This regulator will switch-on when the backup voltage
(see Section “Backup circuit”) exceeds 7.5 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.
Pin RES1 will go HIGH via an internal pull-up resistor of
3.1 k
, and is used to initialize the microprocessor.
Pin 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.
The charge of the backup capacitor can be used to supply
the regulator and logic circuits for a short period of time
whenthesupplyfallsto0 V(thetimedependsonthevalue
of the storage capacitor). The regulator is switched off at a
backup voltage of approximately 2.7 V. From this time
onwards, the backup charge will only be used for
maintaining reset functions. Due to this, the reset outputs
will remain LOW until the output of the regulator is dropped
to 0 V.
All output pins are fully protected. The regulator is
protected against load dump and short-circuit (foldback
current protection). At load dump, the battery detection
circuit will remain operating.
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.
The timing diagrams are shown in Fig.4.
