No Preview Available ! Motor driver ICs Power driver for CD and MD 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 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 inde- pendently for efficient application. 5) Low on-resistance. 6) Low power consumption. 7) Compact SSOP-A32 package.
