LV8414CS
Bi-CMOS LSI
Quad H-Bridge Micro Step
Motor Driver with I2C Interface
www.onsemi.com
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 256-division micro step drive circuit for dual stepper motor
Excitation step proceeds only by step signal input
Peak excitation current switchable to one of 16 levels
Serial data control using I2C interface
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
