BD7907FS

01W138A 6-channel Combo driver IC BD7907FS 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. 13.4±0.3 11.4±0.2 Dimension (Units : mm) 22.0±0.2 54 28 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 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 8) Highly efficient due to the PWM drive 9) Built-in 2-channel for the stepping motor 10) Low noise due to the linear BTL driver and smooth spin 2.2±0.1 0.1 1 27 6.0±0.2 0.8 0.36±0.1 0.1 SSOP-A54 Applications CD-ROM, DVD-ROM, and any other equipment driven by optical DISC Absolute Maximum Ratings (Ta=25˚C) Parameter Power MOS supply voltage Pre/BTL power supply voltage PWM control supply voltage Power dissipation Symbol SPVM1,2, SLRNF1,2 VCC, S...
