Product specification
TDA3606A
FEATURES
• One VP-state controlled regulator
• 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 VP of regulator
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.
