Diodes公司的DMDB2101是BLDC馬達和步進馬達驅動的通用兵功率級，能和馬達控制的所有主流MCU一起工作，板上的電壓穩壓器提供了MCU和霍爾傳感器所需的必要電壓。驅動電路電壓10V-20V，馬達電壓范圍高達60V，馬達電流高達5A，板上提供5V和3.3V電壓源，三個半橋可用于三相BLDC馬達驅動。本文介紹了評估板DMDB2101主要性能，電路圖，材料清單和PCB布局圖。

DMDB2101 is designed to serve as a generic power stage for BLDC and stepper motor driving. This board is designed to work with all the mainstream MCU for motor control applications. Onboard voltage regulators provide necessary voltages rails to the MCU and the hall effect sensors. DMDB2101 is designed to work with MCU using both the back-EMFcontrol algorithm and/or hall-effect sensor input. The modular approach of the board means itcan be easily integrated with different MCU boards and motor units making the developmentprocess fast and easy.

DMDB2101主要性能：

·?Drive Circuit supply voltage （Vcc） range:10V to 20V

·?Motor voltage （VM） range up to 60V（MOSFET limited）

·?Onboard 5V and 3.3V voltage rails

·?Motor current up to 5A （Fuse limited）

·?Three half-bridges for three phase BLDCmotor drive

·?General-purpose power stage for BLDCand stepper motors

·?Back-EMF， Hall sensor， Current feedback to MCU.

·?Dimensions： 69mm*65mm
