applications

BH6514AFS

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.

FApplications

Power drive for CD and MD players

FFeatures
