The BH6514AFS is a PWM driver for CD and MD motors and actuators. In addition to a two-channel “H” bridge for the actuators, the IC includes a three-phase driver for spindle motor drive, and a single-channel half bridge for synchronous rectification of the spindle drive VM.

Features

1) Compatible with PWM input.

2) Charge pump circuit to increase VG.

3) Charge pump circuit has free-running oscillator.

4) Each “H” bridge power supply can be supplied independently for efficient application.

5) Low on-resistance.

6) Low power consumption.

7) Compact SSOP-A32 package.

Applications

Power drive for CD and MD players
