AN8499SH Description
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.
AN8499SH Key Features
- Low-noise, three-phase full-wave PWM drive for spindle motors
- Low current consumption ensured by the five-channel direct PWM system
- High-current D-MOS output with low power dissipation
- Incorporating a short-brake function to suppress heat radiation
- Providing 3x FG output (open-collector type)
- Four power pins can work separately to connect to an independent power supply each
- All channels are driven at 5 V or 12 V
- Incorporating a general-purpose operational amplifier
