Overview
Regulator ICs System power supply for car stereos BA3915B 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.
FApplications Car audio systems FFeatures 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.
FAbsolute maximum ratings (Ta = 25_C) 4) Output current limit circuit prevents damage to the IC due to short-circuiting.
5) Overvoltage prote...
