Jetson nano2g runs yolov4-tiny, “System throttling due to over-current” , nano appears deathn

I use Jetson nano2g with Jetpack4.5.1 and opencv to decode a RTSP video stream, then to run yolov4-tiny, it appears the error message “System throttling due to over-current”,and sometimes it appears death like power off.
(1)power adapter: 5V 4A
(2)only run an algrithm: yolov4-tiny
(3)rtsp stream: use opencv get rtsp stream

I try to search some files to solve this problem, they all show “No such file or directory”.
files:
“/sys/devices/c250000.i2c/i2c-7/7-0040/iio:device0/crit_current_limit_0”,
“/sys/bus/i2c/drivers/ina3221x/6-0040/iio:device0/”,

Moving this topic to the Jetson Nano category for support visibility.
