Overview

The LA5647H power supply IC provides a set of functions optimal for car audio applications. These functions include regulators, emitter-follower outputs, open-collector outputs, and a reset function.

Features

• 5V/50mA regulator (always on, with reverse current flow prevention function).

• 10V/2000mA regulator (when used with an external 2SB921 PNP transistor) with standby function (on/off control).

• Regulators (four for 8V systems and one 5V system) with on/off functions controlled by a shift resister/latch function.

This IC also provides four open-collector output systems and two emitter-follower type output systems.

• Full complement of built-in protection circuits.

1) Overcurrent protection for each VO except the open collector outputs.

2) Thermal protection for each VO except the VDD5V output.
