■ Overview
The AN8497SA is a PWM output 3-channel driver IC supporting linear inputs, and best suited for an actuator and a motor drive for CD-ROM and DVD-ROM. Due to its linear input, a conventional system can be used only by replacing a driver. And, due to an adoption of PWM output, you can reduce considerably power consumption compared with a conventional driver. Further a space saving surface mount package is adopted thanks to its low thermal generation.

■ Features
• Maximum 64% reduction of power consumption compared with a conventional linear 3-channel driver IC
• Free gain setting by an external resistor due to voltage feedback
• Standby function available (standby current < 20 µA)
• Only for supply voltage 5 V
• Phase compensation function

■ Applications
• Optical disk drive
