HA13173AH
Multiple Voltage Regulator for Car Audio
Description
The HA13173AH is a multiple voltage regulator for car audio system. This IC has 5.0 V output for a microcontroller, 3.3 V output for a Digital Signal Processor, 8.0 V output for CD driver, 8.4 V output for audio control, 8.4 V output for illuminations, and high side switch output for external output.
The HA13173AH also has FREG that is possible to control external PNP transistor. It is adjustable output voltage by changing an external resistor.
Functions
• Standby current is 100 µA max.
• The Vdd output for microcontroller has backup function, by independent power supply line.
• Low saturation output (PNP output) used for audio output.
• Output current limit circuit to avoid device destruction caused by shorted output, etc.
• High surge input protector against VB and VBUP.
• Built in a thermal shutdown circuit to prevent against the thermal destruction.
• The package is PRSS0015DA-C (SP-15TGV).
