TDA3608TH Description
TDA3608TH 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.
TDA3608TH Key Features
- 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
