Overview
INTEGRATED CIRCUITS DATA SHEET TDA3618JR Multiple voltage regulator with switch and ignition buffers Preliminary specification Supersedes data of 1999 Jul 13 File under Integrated Circuits, IC01 1999 Sep 01 Philips Semiconductors Preliminary specification Multiple voltage regulator with switch and ignition buffers FEATURES General • Extremely low noise behaviour and good stability with very small output capacitors • Two VP-state controlled regulators (regulators 1 and 3) and a power switch • Regulator 2, reset and ignition buffer operate during load dump and thermal shutdown • Separate control pins for switching regulators (regulators 1 and 3) and the power switch • Supply voltage range of −18 to +50 V • Low reverse current of regulator 2 • Low quiescent current (when regulator 1, regulator 3 and power switch are switched off) • Hold output for low VP (regulators 1 and 3 off) • Hold output for regulators 1 and 3 • Hold output for foldback mode switch • Hold output for load dump and temperature protection • Reset and hold outputs (open collector outputs) • Adjustable reset delay time • High ripple rejection • backup capacitor for regulator 2 • Two independent ignition buffers (one inverted and with open collector output).
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 short circuited) • ESD protected on all pins • Thermal protections with hysteresis ORDERING INFORMATION TYPE NUMBER TDA3618JR PACKAGE NAME DBS17P DESCRIPTION plastic DIL-bent-SIL (specially bent) power package; 17 leads (lead length 12 mm) • Load dump protection TDA3618JR • Foldback current limit protection for regulators 1, 2 and 3 • Delayed second current limit protection for the power switch (at short circuit) • The regulator outputs and the power switch are DC short circuited safe to ground and VP.
GENERAL DESCRIPTION The TDA3618JR is a multiple output voltage regulator with a power swit...
