BH6504K datasheet pdf

226 Optical disc ICs 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.
Applications Portable CD players, MD players
Features 1) Low power consumption. 2) A minimum of attached components. 3) Excellent gain precision because of the voltage feed- back circuit. 4) Internal mute function for channel 1. 5) Allows for free-running and clock synchronization op- eration. 6) Internal standard operational amplifier. 7) Internal charge pump circuit for gate drive. 8) Switchable to doubled clock synchronization.
