Stepping Motor Driver for Automotive

BD63800MUF-C

General Description

Key Specifications

BD63800MUF-C is a bipolar low-consumption driver that

is driven by PWM current. Rated power supply voltage of

the device is 40 V, and rated output current is 1.35 A.

BD63800MUF-C has two input interface as driving mode:

CLK-IN and SPI-IN, and six excitation modes: Full step,

1/2, 1/4, 1/8, 1/16 and 1/32 step. Mix Decay Mode: the

seamless adjustment function of slow/fast decay ratio,

and Auto Decay Mode: Automatic switching function of

slow/fast decay, can realize the optimized control status

for all kinds of motor. In addition, BD63800MUF-C

operates with single power supply which can simplify the

set design.
