LV8414CS

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.

.

Feature

 Built-in thermal protection circuit

 Low supply voltage protection circuit incorporated

 On-chip photo sensor drive transistors

 On-chip Schmitt buffer

Typical Applications

 Tablet

 Digital Still Camera

 Feature Phone

 Smartphone
