INTEGRATED CIRCUITS DATA SHEET TDA3616 Multiple voltage regulator with battery detection Objective specification Supersedes data of 1998 Jul 22 File under Integrated Circuits, IC01 2000 Jan 14 Philips Semiconductors Objective specification Multiple voltage regulator with battery detection 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.

GENERAL DESCRIPTION TDA3616 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 ...
