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
