LV8728MR-AH

The LV8728MR-AH is a PWM current-controlled microstep stepper motor driver in MFP30KR package. The LV8728MR is a PWM current-controlled micro step stepper motor driver. This driver can perform eight types of excitation mode from full step to 1/128 step and can drive simply by the CLK input. LV8728MR is suitable for various applications to have an abundant excitation mode. It has built-in overcurrent protection thermal shutdown and low voltage protection circuit. Typical applications include printer (multi-function printer, 3D printer, etc.), security camera, scanner and stage light.
