BA3918 datasheet

 

Description

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.

Block Diagram :

components

Features

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.

 

Applications:

1) Car audio systems
