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
