BTL driver for CD/CD-ROM
BA5995FM
The BA5995FM is 4-channel BTL driver IC for driving actuator and motor of CD-ROM. Power package of HSOP-M28 pin
enables to make set smaller. This IC is available for low voltage DSP.

2) Thermal shut down circuit built in.
3) Separating V
CC
into Pre and Power (Power divides into CH1, 2 and CH3/4), can make better power efficiency, by low
supply voltage drive.
4) Stand by operated individually CH2 and CH1/3/4.
5) Built-in mute(CH1) circuit.
6) Suitable for low operation voltage DSP by wide D-range pre opamp.
