HA13164A

HA13164A Multiple Voltage Regulator ADE-207-342 (Z) Rev.0 Jun. 2001 General Description The HA13164A is a compact multiple voltage regulator for car audio system. The outputs of this IC output consist of regulated 5.7 V output for a microcontroller, regulated 8 V output for CD driver, regulated 9.0 V output for audio control, regulated 10 V output for illuminations and regulated 5 V output, VCC-dependent output for external output and VCC-dependent output for remort-ANT. Functions General ACC power monitor circuit is built-in as to detect low voltage. Low saturation output (PNP output) used for audio output. Adjustable voltage for illumination output by changing an external resister. Protections Output current limit circuit to avoid device destruction caused by shorted output, etc. High surge input protector against VCC and ACC. Built in a thermal shutdown circuit to prevent against the thermal destruction.
