HA13164AH
Multiple Voltage Regulator for Car Audio
REJ03F0139-0200 Rev.2.00 Jan 16, 2007
Description
The HA13164AH 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 remote-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 resistor. 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.
