TDA3609JR Datasheet PDF

NXP Semiconductors TDA3609JR

The TDA3609JR is a multiple output voltage regulator with a power switch and ignition buffers, intended for use in car radios with or without a microcontroller. It contains: • Two fixed voltage regulators with a foldback current protection (regulator 1 and regulator 3) and one fixed voltage regulator (regulator 2), intended to supply a microcontroller, that 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 by the microcontroller. The reset-signal can be used to call up the microcontroller and the hold output indicates regulator 1 voltage available and within range.
