■ 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
