TDA3609JR

INTEGRATED CIRCUITS DATA SHEET TDA3609JR Multiple voltage regulator with switch and ignition buffers Preliminary specification File under Integrated Circuits, IC01 1997 Aug 15 Philips Semiconductors Preliminary specification Multiple voltage regulator with switch and ignition buffers FEATURES General Extreme low noise behaviour and good stability with very small output capacitors Two VP-state controlled regulators (regulator 1 and regulator 3) and a power switch Regulator 2, reset and ignition buffer operate during load dump and thermal shutdown Separate control pins for switching regulator 1, regulator 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 (only valid when regulator 1 is switched-on) Reset and hold outputs (open collector outputs) Adjustable reset delay time High ripple rejection Back-up 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 Load dump protection Foldback current limit protection for regulators 1, 2 and 3 Delayed second current limit protection for the power switch (at short-circuit) ...
