描述
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.

BD65520MUV  
General Description  
Key Specifications  
BD65520MUV is a 36 V power supply rated, 2.0 A 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.
