BD7905BFS Overview
BD7905BFS Optical disc ICs 6CH Power Driver for CD-ROM, DVD-ROM BD7905BFS 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.
BD7905BFS Key Features
- 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
- ON/OFF of loading, and other 5channels, brake mode and gain select of spindle driver and standby mode. 3) Built-in trian
- Efficient drive by current feedback 180deg PWM drive
- Built in current limit, hall bias, short brake, FG 3-phase mixed signal output and reverse protection circuit
- Low ON-Resistor. (RON=0.85Ω) 〈 Sled motor driver 〉
- Efficient drive by current feedback PWM drive
- Built in 2channel for stepping motor. 〈 Actuator driver, Loading driver 〉
- Linear BTL drive system
