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 systems are built in.
2) All output circuits use a
PNP transistor with a low saturation voltage.
3) Output current limit circuit prevents damage to the IC in the event output is short-circuited.
