Optical disc ICs
PWM driver for CD and MD players
BH6505K
The BH6505K is a 4-channel PWM driver designed for CD and MD player motor and actuator drives. The power MOS-
FET 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.
Applications
Portable CD players, MD players
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 op-
eration.
6) Internal standard operational amplifier.
7) Internal charge pump circuit for gate drive.
Absolute maximum ratings (Ta = 25 C)
Recommended operating conditions
