Description



Features:

1) Motor drivers for spindle, sled (2-channel) and 
    loading, and actuator drivers for tracking are all 
    integrated into a single chip. 
2) ON/OFF for each driver, brake mode switching of spindle and stand-by mode switching can be controlled by 2-wire serial data.      
3) Built-in triangular-wave generator
4) SSOP-A54 package
5) Built-in thermal shut-down circuit
<Spindle driver>
6) Highly efficient by applying the PWM drive and Low ON resistance POWER MOSFET
7) Built-in current limit, hall bias, short brake, FG 3-phase synthesis output, and reverse protection circuit
<Sled motor driver>
8) Highly efficient due to the PWM drive
9) Built-in 2-channel for the stepping motor
<Actuator, loading driver>
10) Low noise due to the linear BTL driver and smooth spin


Application

CD-ROM, DVD-ROM, and any other equipment driven by optical DISC

Description

BD7907FS is a 6-channel driver IC that integrates all drivers necessary for CD-ROM, and DVD-ROM systems into a single chip.  The built-in 2-channel sled motor driver is used for the stepping motor.  Low heat operation can be achieved by applying the PWM driving system for sled and spindle motor drivers.
