The BH6505K is a 4-channel PWM driver designed for CD and MD player motor and actuator drives. The power MOSFET output stage allows for applications with low power consumption. This IC also has a charge pump circuit and standard operational amplifier (needed for power MOSFET gate drives), and so supports a wide spectrum of applications.

Features
1) Low power consumption.
2) A minimum of attached components.
3) Good gain precision because of the voltage feedback circuit.
4) Internal mute function for channels 1 and 2.
5) Allows for free-running and clock synchronization operation.
6) Internal standard operational amplifier.
7) Internal charge pump circuit for gate drive.

Applications
   Portable CD players, MD players
