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 transistor 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 ACC or BACKUP input.
4) Compact 12-pin POWER package allows large power dissipation.
5) Thermal protection circuit prevents heat damage to the IC.
