BH6546KV Datasheet (Rohm) - One chip driver for slim CD-ROM/RW/ DVD-ROM

BH6546KV, One chip driver for slim CD-ROM/RW/ DVD-ROM

BH6546KV is a 4-channel PWM driver that drives spindle/slide motor, and focus/track actuator coil of optical disc.

In high speed and 180˚ PWM driving slim disc, the spindle driver can achieve low vibration/low noise.
