BD63800MUF-C
40V Max, Low-Consumption Bipolar, PWM Current Drive Stepping Motor Driver for Automotive
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.
