Description

The HA13168H 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, 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.

• A reset signal output for a microcontroller.

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.
