Overview
INTEGRATED CIRCUITS DATA SHEET TDA3603 Multiple voltage regulator with switch Product specification Supersedes data of 1995 Oct 04 File under Integrated Circuits, IC01 1997 Aug 15 Philips Semiconductors Product specification Multiple voltage regulator with switch FEATURES General • One VP state controlled regulator (regulator 2) • Regulator 2, reset and ignition buffer operate during load dump and thermal shutdown • One control pin for switching regulator 1 and the power switch • Supply voltage range of −18 to +50 V (operating from 9.
75 V) • Low reverse current of regulator 2 • Low quiescent current (when regulator 1, power switch and ignition input are switched off, standby) • Ignition input/output • Reset output • High ripple rejection • Power switch.
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 shortened) • ESD protected on all pins • Thermal protection • Load dump protection • Foldback current limit protection for regulators 1 and 2 • Delayed second current limit protection for the power switch • The regulator outputs and the power switch are DC short-circuited safe to ground and VP.
ORDERING INFORMATION PACKAGE TYPE NUMBER NAME TDA3603 TDA3603P SIL9MPF HDIP18 DESCRIPTION plastic single in-line medium power package with fin; 9 leads plastic heat-dissipating dual in-line package; 18 leads GENERAL DESCRIPTION TDA3603 The TDA3603 is a multiple output voltage regulator with a power switch, intended for use in car radios with or without a microcontroller.
It contains one fixed voltage regulator with a foldback current protection (regulator 1) and one fixed voltage regulator (regulator 2), intended to supply a microcontroller, that also operates during load dump and thermal shutdown.
There is a power switch with protections, operated by the enable input.
The reset and ignition outputs can be used to interface by the microcontroller.
The reset signal can b...
