TDA3616 Datasheet | NXP Semiconductors

FEATURES General - One VP-state controlled regulator - Battery detection circuit - Regulator, reset and battery outputs operate during load dump - Supply voltage range from - 18 to +50 V - Low quiescent current (battery detection switched off) - High ripple rejection - Dual reset output - Backup circuit - Adjustable reset delay timer. 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 - The regulator output is DC short-circuited safe to ground and VP.

TYP. GENERAL DESCRIPTION The TDA3616 is a low power voltage regulator. It contains the following: - 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.
