2 / 20 page  1997 Aug 15 2 Philips Semiconductors Product specification Multiple voltage regulator with switch TDA3603 FEATURES General • One V P 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. GENERAL DESCRIPTION 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 be used to call up the microcontroller and the ignition output indicates ignition voltage available. The supply pin can withstand load dump pulses and negative supply voltages. Regulator 2 will be switched on at a supply voltage >6.5 V and off at a voltage of regulator 2 <1.9 V.
