Product Details

Description



Features:

1) ACC and BACKUP voltages are monitored,
  compared with the internally set values; one-shot
  pulses are output to MUTE, which synchronizes with
  the rising and falling of the STANDBY input.
2) ACC voltage is monitored, compared with the internally
  set value, and the result is output to ACCB.
3) All outputs use a PNP transistor with low saturation voltage.
4) Output current limit circuit prevents damage to the IC
  due to short-circuiting.
5) Overvoltage protection circuit provides protection
  against surges from the ACC or BACKUP input.
6) Compact 16-pin POWER package allows large power dissipation.

Description

The BA3915B is an one-chip power supply IC for use in car audio systems. The IC has seven output systems : one 5V output (VDD), four 8.5V outputs (COM, FM, AM, AR), and two high-side switch outputs (ANT, AMP). The 5V outputs operate all the time if only the BCAD input is provided. The other outputs operate with BACKUP and ACC inputs, and their ON / OFF is controlled by the STANDBY and MODE inputs.
