Product specication
Multiple voltage regulators with switch
TDA3608Q; TDA3608TH
FEATURES
General
Two VP-state controlled regulators (regulator 1 and
regulator 3) and a power switch
Regulator 2 and reset circuit operate during load dump
and thermal shutdown
Separate control pins for switching regulator 1,
regulator 3 and power switch
Supply voltage range from 18 to +50 V
Low reverse current of regulator 2
Low quiescent current (when regulator 1, regulator 3
and power switch are switched off)
Hold output circuit for regulator 1 (only valid when
regulator 3 output voltage >1.3 V)
Reset and hold outputs (open-collector outputs)
Adjustable reset delay time
High ripple rejection
Backup capacitor connection to supply regulator 2 and
reset circuit up to 25 V.
Protections
Reverse polarity safe (down to 18 V without high
reverse current)
Able to withstand voltages up to 18 V at the outputs
(supply line may be short circuited)
ESD protection on all pins
Thermal protection
Load dump protection
Foldback current limit protection for regulator 1,
regulator 2 and regulator 3
Delayed foldback current limit protection for power
switch (at short-circuit); delay time fixed by reset delay
capacitor
All regulator outputs and power switch are
DC short-circuited safe to ground and VP.
GENERAL DESCRIPTION
The TDA3608 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 output voltage regulators with a foldback
current protection (regulator 1 and regulator 3) and one
fixed output voltage regulator (regulator 2) intended to
supply a microcontroller, which 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
with the microcontroller; the reset output can be used to
call up the microcontroller and the hold output indicates
that the regulator 1 output voltage is available and within
the range
A supply pin which can withstand load dump pulses and
negative supply voltages
Regulator 2 which is switched on at a backup voltage
higher than 6.5 V and switched off when the regulator 2
output drops below 1.9 V
A provision for the use of a reserve (backup) supply
capacitor that will hold enough energy for regulator 2
(5 V continuous) to allow a microcontroller to prepare for
loss of voltage.
