TDA3602

INTEGRATED CIRCUITS DATA SHEET TDA3602 Multiple output voltage regulator Product specification File under Integrated Circuits, IC01 July 1994 Philips Semiconductors Product specification Multiple output voltage regulator FEATURES Two VP state controlled regulators (REG1 and REG2) Regulator 3 operates during load dump or thermal shutdown Multi-function control pin A back-up circuit for Regulator 3 via a single capacitor Supply voltage of −6 V to 50 V (a voltage of −3 V on VP does not discharge capacitor Cbu) Low reverse current Regulator 3 Low quiescent current in coma mode HOLD output RESET output (LOW at load dump) High ripple rejection. PROTECTIONS Foldback current limit protection (Regulators 1 and 2) Load dump protection Thermal protection DC short-circuit safe to ground and VP of all regulator outputs Reverse polarity safe of pin 1 (VP). No high currents are flowing which can damage the IC Capable of handling high energy on the regulator outputs. GENERAL DESCRIPTION TDA3602 The TDA3602 is a multiple output voltage regulator, intended for use in car radios with or without a microprocessor. It contains two fixed voltage regulators with foldback current protection (Regulators 1 and 2), and one fixed voltage regulator that also operates during load dump and thermal shutdown. This regulator can be used to supply a microprocessor. A back-up circuit supplies Regulator 3 during a short period after the power is cut off (negative field decay o...
