BD7905BFS General Description
BD7905BFS is a 6-channel driver IC that integrates all drivers necessary for optical disc driver. Low vibration, low noise, and low heat operation have been realized by adopting 180° PWM driving system for spindle motor driver. The built-in 2-channel sled motor driver is used for the stepping motor.
