Datasheet 36VHigh-performance, High-reliability Withstand V oltage Stepping Motor Driver BD63715AEFV General Description Major Characteristics BD63715AEFV is a bipolar low-consumption driver that Range of power supply voltage 1928 V driven by PWM current. Rated power supply voltage of Rated output current (continuous) 1.5 A the device is 36 V, and rated output current is 1.5 A. Rated output current (peak value) 2.0 A CLK-IN driving mode is adopted for input interface, and Range of operating temperature -25+85 excitation mode is corresponding to FULL STEP mode, Output ON resistance (total of 0.95 (Typ.) HALF STEP mode (2 types) and QUARTER STEP upper and lower resistors) mode via a built-in DAC. In terms of current decay, the FAST DECAY/SLOW DECAY ratio may be set without Package W(Typ.) x D(Typ.)x H(Max.) any limitation, and all available modes may be HTSSOP-B28 9.70mm x 6.40mm x 1.00mm controlled in the most appropriate way. In addition, the power supply may be driven by one single system, which simplifies the design.
