AN8497SA
3-channel linear input PWM driver IC
s
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.
