Diodes公司的DMDB2101是BLDC马达和步进马达驱动的通用兵功率级,能和马达控制的所有主流MCU一起工作,板上的电压稳压器提供了MCU和霍尔传感器所需的必要电压.驱动电路电压10V-20V,马达电压范围高达60V,马达电流高达5A,板上提供5V和3.3V电压源,三个半桥可用于三相BLDC马达驱动.本文介绍了评估板DMDB2101主要性能,电路图,材料清单和PCB布局图.
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
