AN8499SH

New AN8499SH IC for Driving Optical Disc Motors n Overview The AN8499SH is an IC that incorporates 5-channel fullPWM drive circuit ideal for optical disc drive applications, such as CD-ROM, DVD-ROM, CD-RW, and DVD-RAM drives. Panasonic's newly developed circuit design applied to this IC ensures smooth spindle motor driving with the reduction of current consumption and noise generation n Feature l Low-noise, three-phase full-wave PWM drive for spindle motors. l Low current consumption ensured by the five-channel direct PWM system. l High-current D-MOS output with low power dissipation. l Incorporating a short-brake function to suppress heat radiation. l Providing 3x FG output (open-collector type) l Four power pins can work separately to connect to an independent power supply each. l All channels are driven at 5 V or 12 V. l Incorporating a general-purpose operational amplifier. l Incorporating a thermal protection circuit. l Compact, thin power package with 0.5-mm-pitch lead pins emp...
