TDA3681 Multiple Voltage Regulator With Switch And Ignition Buffer

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.
