Product specification

Multiple voltage regulator with battery

detection

TDA3606A

FEATURES

• Regulator and reset outputs operate during load dump

• Supply voltage range of −18 to +50 V

• Low quiescent current (battery detection switched off)

• High ripple rejection

• Dual reset output.

PROTECTIONS

• Reverse polarity safe (down to −18 V without high

reverse current)

• Able to withstand voltages up to 18 V at the output

(supply line may be short-circuited)

• ESD protected on all pins

• Load dump protection

• Foldback current limit protection for regulator

• DC short-circuit safe to ground and V

output.

GENERAL DESCRIPTION

The TDA3606A is a low power voltage regulator.

It contains:

1. One fixed voltage regulator with a foldback current

protection, intended to supply a microprocessor, that

also operates during load dump

2. A reset-signal can be used to interface with the

microprocessor

3. Supply pin can withstand load dump pulses and

negative supply voltages

4. Defined start-up behaviour; regulator will be switched

on at a supply voltage higher than 7.6 V and off when

the output voltage of the regulator drops below 2.4 V.
