2 / 22 page 2003 Nov 28 2 Philips Semiconductors Product specification Multiple voltage regulators with switch TDA3608Q; TDA3608TH FEATURES General • Two VP-state controlled regulators (regulator 1 and regulator 3) and a power switch • Regulator 2 and reset circuit operate during load dump and thermal shutdown • Separate control pins for switching regulator 1, regulator 3 and power switch • Supply voltage range from −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 circuit for regulator 1 (only valid when regulator 3 output voltage >1.3 V) • Reset and hold outputs (open-collector outputs) • Adjustable reset delay time • High ripple rejection • Backup capacitor connection to supply regulator 2 and reset circuit up to 25 V. 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 protection on all pins • Thermal protection • Load dump protection • Foldback current limit protection for regulator 1, regulator 2 and regulator 3 • Delayed foldback current limit protection for power switch (at short-circuit); delay time fixed by reset delay capacitor • All regulator outputs and power switch are DC short-circuited safe to ground and VP. GENERAL DESCRIPTION The TDA3608 is a multiple output voltage regulator with a power switch, intended for use in car radios with or without a microcontroller. It contains: • Two fixed output voltage regulators with a foldback current protection (regulator 1 and regulator 3) and one fixed output voltage regulator (regulator 2) intended to supply a microcontroller, which also operates during load dump and thermal shutdown • A power switch with protections, operated by an enable input • Reset and hold outputs that can be used to interface with the microcontroller; the reset output can be used to call up the microcontroller and the hold output indicates that the regulator 1 output voltage is available and within the range • A supply pin which can withstand load dump pulses and negative supply voltages • Regulator 2 which is switched on at a backup voltage higher than 6.5 V and switched off when the regulator 2 output drops below 1.9 V • A provision for the use of a reserve (backup) supply capacitor that will hold enough energy for regulator 2 (5 V continuous) to allow a microcontroller to prepare for loss of voltage. ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION TDA3608Q DBS13P plastic DIL-bent-SIL power package; 13 leads (lead length 12 mm) SOT141-6 TDA3608TH HSOP20 plastic, heatsink small outline package; 20 leads; low stand-off height SOT418-3 |
