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 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. FApplications Portable CD players, MD players FFeatures 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. FAbsolute maximum ratings (Ta = 25_C) 5) Allows for free-running and clock synchronization operation. 6) Internal standard operational amplifier.
