Product Details
__
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.
Features
1) 3channel BTL driver, 2channel PWM driver and 3phase motor driver.
- ALL of the motor and actuator for CD-ROM, DVD-ROM etc.
2) These mode is able to be selected by the two control terminals.
