... PWM driver for CD and MD players BH6504K The BH6504K is a 4-channel PWM driver designed for CD and MD player motors and actuator drives. The power MOF- SET output stage allows for applications with low power consumption. This IC also has a charge pump circuit and stan- dard operational amplifier (needed for power MOSFET gate drives), and so supports a wide spectrum of applications ...
