Bi-CMOS IC
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
