Other Parts Discussed in Thread: BQ40Z50
我们的采用电阻为1mR,但是经过电流校准后,采用电阻阻值变成了2.454mR
同时当我们使用SMBC与SMBD与其他载板通信时,其MCU异常短路烧毁
您好
Could you elaborate on which pin you are refering?
IOs for the SMBus should be within specs, and shouldnt burn other host as long the pull up voltage on the bus line are correct. Do you know if the MCU ios are push-pull or open-drain? The IOs for SMBus on bq40z50 should be open drain.
