HA13164A

Multiple Voltage Regulator

ADE-207-342 (Z)

Rev.0

Jun. 2001

General Descrip tion

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 lo w voltage.

• Low saturation output (PNP output) used for audio output.

• Adjustable voltage for illumination output by changing an external resister.

P rotec tions

• 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.
