Regulator ICs
System power supply for car stereos
BA4900
The BA4900 is a single-chip power supply IC for use in car stereo audio systems. The IC contains one 5.8V output for
a microcontroller, three 8V outputs, one 10V output, and two outputs interlocked with BACKUP and ACC systems.
Applications
Car stereo audio systems
Features
1) All output circuits, except AMP and ANT circuits, use
a PNP transistor with a low saturation voltage.
2) Output current limit circuit prevents damage to the IC
in the event output is short-circuited.
3) Overvoltage protection circuit provides protection
against surges from the ACC or BACKUP inputs.
4) Compact 12-pin POWER package allows a large
power dissipation.
5) Thermal protection circuit prevents heat damage to
the IC.
Absolute maximum ratings (Ta = 25 C)
Recommended operating conditions (Ta = 25 C)
