36V

2ch Stepping Motor Driver

BD68888MUV

General Description

Key Specifications

BD68888MUV is a bipolar low-consumption driver that

driven by PWM constant current. Rated power supply

voltage of the device is 36 V, and rated output current is

1.65 A. PARA-IN drive mode is adopted for input

interface. This motor driver can drive 2ch bipolar

stepping motors.
