BH6541KV General Description
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.
