NCF29A1 motion detect pin configuration

Eternal — Tue, 10 May 2022 14:35:28 GMT

Hello，I am using P21_MD of NCF29A1 as motion detect. but I find a problem that when the motion sensor works, a high level pulse will be triggered, which will cause a large increase in power consumption. (Normal standby power consumption is 19uA, motion sensor operating power consumption is 400uA)

At this time, the power consumption is not consumed by the motion sensor, because when I disconnect the resistance of MU1R7, the overall power consumption will not increase when the motion sensor works, so it should be caused by the port of P21_MD.

How should I configure the ports of P21_MD and software in this part to ensure that the power consumption of the ports will not be too high when the motion sensor works?

the NCF family is part of the Keyless product, you need to contact your local sales to get support for this device.
