The BH6504K is a 4-channel PWM driver designed for CD and MD player motors and actuator drives. The power MOFSET 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) Excellent gain precision because of the voltage feedback circuit.

4) Internal mute function for channel 1.

5) Allows for free-running and clock synchronization operation.

6) Internal standard operational amplifier.

7) Internal charge pump circuit for gate drive.

8) Switchable to doubled clock synchronization.

Applications

Portable CD players, MD players
