Bi-CMOS IC
LV8414CS
Microstep Driver Motor Driver IC
Overview
The LV8414CS is a motor driver IC that incorporates two channels of PWM constant-current control micro-step
drivers. 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.
Features
Two channels of 256-division micro-step drivers
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
