GENERAL DESCRIPTION
The TDA3616 is a low power voltage regulator. It contains
the following:
18 V; T
18 V
r
50 V; load dump
One fixed voltage regulator with a foldback current
protection, intended to supply a microprocessor, that
also operates during load dump
A provision for use of a reserve supply capacitor that will
hold enough energy for the regulator to allow a
microcontroller to prepare for loss of supply voltage
Reset signals which can be used to interface with the
microprocessor
A supply pin that can withstand load dump pulses and
negative supply voltages
Defined start-up behaviour; regulator will be switched on
at a supply voltage higher than 7.5 V and off when the
output voltage of the regulator drops below 2.4 V.
