onsemi LV8549MCGEVB Evaluation Board
onsemi LV8549MCGEVB Evaluation Board is a 2-channel full-bridge driver IC evaluation board. This evaluation board evaluates the LV8549M low saturation voltage forward/reverse motor driver that is optimal for a full-step motor drive in 12V system products.
Features
- Incorporates a single-channel PWM current control stepping motor driver (selectable with DC motor driver channel 2)
- BiCMOS process IC
- Micro-step mode can be set to full-step, half-step (full torque), half-step, and quarter-step mode
- Excitation step proceeds only by step signal input
- Motor holding current selectable in 4x steps
- 1.5A maximum I/O
- Output-stage push-pull structure enabling high-speed operation
- Incorporates an output short-circuit protection circuit (selectable from latch-type or auto reset-type)
- Incorporates thermal shutdown circuit and power supply monitor circuit incorporated
- Supports 3.3VCC control power supply
