GENERAL DESCRIPTION
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.
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.
