4-channel PWM driver for CD
and MD use
BH6512FS / BH6513FS
The BH6512FS / BH6513FS are 4-channel PWM drivers for driving the motors and actuators in CD and MD players.
MOSFET output stages are employed to keep power consumption down, and a charge pump circuit is included to multi-
ply the VG voltage.
