Overview
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.
