Reference voltage power supply

BA3911

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.

FApplications

Car audio systems

FFeatures

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 sys-

tems are built in.

2) All output circuits use a PNP transistor with a low sat-

uration 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.
