描述 Description

The LV8728MR is a PWM current-controlled micro step stepper motor driver. This driver can perform eight excitation modes from Full step to 1/128 step and can drive simply by the CLK input. LV8728MR is suitable for various application to have an abundant excitation mode. And overcurrent protection, thermal shutdown, and low-voltage protection circuit is built-in, it is possible to design safely as customer's application.
