Reference voltage power supply

The BA3911 is a single-chip power supply IC for use in car audio systems. One 5.6V output for microcontrollers, three 8.7V outputs, and two outputs interlocked with BACKUP and ACC systems are built in.

Features

1) A power supply IC for car audio systems ; one 5.6V output for microcontrollers, three 8.7V outputs, and

two outputs interlocked with BACKUP and ACC systems are built in.

2) All output circuits use a PNP transistor with a low saturation voltage.

3) Output current limit circuit prevents damage to the IC in the event output is short-circuited.

4) Overvoltage protection circuit provides protection against surges from the ACC or BACKUP inputs.

5) Compact 12-pin POWER package allows a large power dissipation.

6) Thermal protection circuit prevents heat damage to the IC.
