LV8414CS: Quad H-Bridge Micro Step Motor Driver with I2C Interface
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.
Features- Serial data control using I2C interface
- Built-in thermal protection circuit
- Low supply voltage protection circuit included
- 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
- On-chip photo-sensor drive transistor
- On-chip Schmitt buffer
| Benefits- Easy control
