Power driver for portable CD BH6541KV DescriptionDimension (Units : mm) Features Applications BH6541KV is a 3chPWM driver + 1ch sensorless spindle driver developed for driving motor and actuator of portable CD,MD. Lower power consumption can be achieved in the set by applying the power MOSFET. In addition, the size reduction in the set can be accomplished by using the VQFP48 package. 00W149A <PWM driver: 3ch> 1) Digital input, Direct PWM driving system <Spindle driver> 1) 3-phase full-wave sensorless driving system 2) Built-in start and brake function 3) Built-in half-bridge driver for power supply
