Regulator ICs
System power supply for car stereos
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) pact 12-pin POWER package allows large power dissipation. 5) Thermal protection circuit prevents heat damage to the...
