System power supply for car stereos

BA3918

The BA3918 is a single-chip power supply IC for use in car audio systems. One 5.6V output for a microcontroller, three

8.7V outputs, and two outputs interlocked by BACKUP and ACC systems are built in.

FApplications

Car audio systems

FFeatures

1) All outputs except AMP and ANT use a PNP transis-

tor with a low saturation voltage.

2) Output current limit circuit prevents damage to the IC

due to short-circuiting.

3) Overvoltage protection circuit provides protection

against surges from the A

CC

or BACKUP input.

4) Compact 12-pin POWER package allows large pow-

er dissipation.

5) Thermal protection circuit prevents heat damage to

the IC.
