Quad H-Bridge Micro Step Motor Driver with I2C Interface
.onsemi.
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. .
