Overview
The LV8414CS is a motor driver that is available for the PWM
constant-current control micro step drive of dual stepper motor.
Miniaturization using the wafer level package (WLP) makes the IC
ideally suited for driving the stepping motors used to control the lenses
in digital still cameras, cell phone camera modules and other such
devices.
.
