TDA3608Q; TDA3608TH
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.
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 .
