BD65520MUV (Under Development)
High-efficiency 36V Withstand Voltage Stepping Motor Driver
BD65520MUV is a 36V power supply rated, 2.0A output current rated, low-consumption bipolar PWM constant current driven High-efficiency Driver. The input interface adopts the CLK-IN drive system, and the excitation mode supports FULL STEP to 1/32 STEP mode via a built-in DAC. FAST / SLOW DECAY of current decay mode ratio linear variable freely. Pin settings and detailed settings by SPI are set to make an optimum current control possible according to the load of every motor for a High-efficiency Drive. In addition, the power supply may also be driven by a single system, contributing to a simple set design.
