BD7904FS

www.DataSheet4U.com BD7904FS Optical disc ICs 5ch Power Driver for CD-ROM, DVD-ROM BD7904FS BD7904FS is a 5-channel driver IC that integrates all drivers and 3.3V regulator necessary for CD-ROM, and DVD-ROM systems into a single chip. Low head operation can be achieved by applying the PWM driving system for sled and spindle motor drivers. !Applications CD-ROM, DVD-ROM !Features 1) 3channel BTL driver, 1channel PWM driver and 3phase motor driver. - ALL of the motor and actuator for CD-ROM, DVD-ROM etc. 2) ON/OFF for each driver, brake mode switching of spindle, and stand-by mode switching can be controlled by the two control terminals. 3) Built-in triangular-wave generator. 4) SSOP-A54 for strong head radiation. 5) Built in thermal-shut-down circuit. 6) FG 3phase synthetic output. !Absolute maximum ratings (Ta=25°C) Parameter POWER MOS power suuply voltage Preblock/BTL powerblock power supply voltage PWM control block, REG power supply voltage Power dissipation Operating temperature range Storage temperature Symbol SPVM1,2,SLRNF VCC,SLVDD,AVM DVCC Pd Topr Tstg Limits 15∗1 15 7 2.6∗2 −35~+85 −55~+150 Unit V V V W °C °C ∗1 POWER MOS output terminals (10, 11, 18, 47, 48pin) is contained. ∗2 PCB (70mm×70mm×1.6mm glass epoxy) mounting.
