Microchip CP8025三相BLDC马达驱动器解决方案
Microchip公司的CP8025/6是集成了功率模块,睡眠模式和LIN收发器的三相无刷DC(BLDC)马达驱动器,包括有能驱动三个外接NMOS/NMOS晶体管对的三个半桥驱动器,峰值输出电流在12V时为0.5A,具有击穿保护电路,过流保护和短路保护功能,睡眠模式电流5uA,待机模式小于200uA.本文介绍了MCP8025/6主要特性,框图和典型应用电路,以及MCP8025 三相BLDC马达驱动评估板主要特性,框图,电路图,PCB元件布局图和材料清单与PCB走线图.
The MCP8025/6 devices are 3-phase brushless DC (BLDC) power modules containing three integrated half-bridge drivers capable of driving three external NMOS/NMOS transistor pairs. The three half-bridge drivers are capable of delivering a peak output current of 0.5A at 12V for driving high-side and low-side NMOS MOSFET transistors. The drivers have shoot-through, overcurrent and short-circuit protection. A Sleep Mode has been added to achieve a typical “key-off” quiescent current of 5 μA.
