More about TDA3681

The TDA3681 is a multiple output voltage regulator with a power switch and an ignition buffer. It is intended for use in car radios with or without a microcontroller. The TDA3681 contains the following:

  • Four fixed voltage regulators with a foldback current protection (regulators 1, 2, 3 and 4). Regulator 2, which is intended to supply a microcontroller, also operates during load dump and thermal shutdown
  • Regulators 3 and 4 have a second supply pin that can be connected to a lower supply voltage (>6.5 V) to reduce the power dissipation
  • A power switch with protection, operated by a control input
  • Reset and hold outputs that can be used to interface with the microcontroller; the reset signal can be used to call up the microcontroller
  • Both supply pins can withstand load dump pulses and negative supply voltages
  • Regulator 2, which is in regulation at a backup voltage above 6.5 V
  • A provision for the use of a reserve supply capacitor that will hold enough energy for regulator 2 (5 V continuous) to allow a microcontroller to prepare for loss of voltage
  • An ignition input Schmitt trigger with push-pull output stage.
