GENERAL DESCRIPTION
The TDA3608Q is a multiple output voltage regulator with
a power switch, intended for use in car radios with or
without a microcontroller. It contains:
Two fixed voltage regulators with a foldback current
protection (regulator 1 and regulator 3) and one fixed
voltage regulator (regulator 2), intended to supply a
microcontroller, that also operates during load dump
and thermal shutdown.
A power switch with protections, operated by an enable
input
Reset and hold outputs that can be used to interface by
the microcontroller. The reset signal can be used to call
up the microcontroller and the hold output indicates
regulator 1 voltage available and within range.
A supply pin which can withstand load dump pulses and
negative supply voltages
Regulator 2 that will be switched on at a back-up voltage
higher than 6.5 V and off when the output voltage of
regulator 2 drops below 1.9 V
A provision for use of a reserve supply capacitor that will
hold enough energy for regulator 2 (5 V continuous) to
allow a microcontroller to prepare for loss of voltage.
