Product Overview
Описание продукта
The LV8772 is a stepping motor driver, which is capable of micro-step drive and supports 4W 1-2 phase excitation. It has Low On Resistance with motor current selectable in four steps. The LV8772 is equipped with unusual condition warning output pins and output short-circuit protection feature to enhance the safety of the application. It is most suitable for the drive of a stepping motor for OA, amusements.
