4-channel BTL driver for car CD players
BA5993FP
Description
The BA5993P incorporates 4-channel drivers that
operate the motor and actuator for car CD players.
CH1, 2, and CH3, 4 each have power supply
independently. The highly efficient drive can be
achieved due to the low voltage operation.
Features
1) Built-in 3.3V regulator
2) Built-in standard operational amplifier
3) Built-in mute function
3 lines (CH1,2, CH3 and CH4)
4) Reference voltage can be changed into external
input voltage and internal voltage.
5) Built-in thermal shut down circuit
