Other Parts Discussed in Thread: TPS3820,
Dear TI Experts,
I am using TPS3820-50 to monitor voltage~
And when doing test, I find that when it is -40℃, it will reset~ Other temperature all works good~
The wave is as below, Yellow→reset, Blue→WDI~
The first picture is abnormal situation,and the second picture is normal situation
I guess it‘s WDI that causes the reset~(time out)
But when I use TPS3820-33, it works well in all temperature~
Is it the MCU or the TPS3820 -50's abnormal that cause the reset when in -40℃?
