Part Number: TPS3820-Q1 Hi team
If the MCU keeps the WDI pin high, is it happen reset?
I checked reset status when the WDI pin keeps low.
But I didn't see status of reset pin when the WDI pin keeps high.
Thank you
Part Number: TPS3820-Q1 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…
Part Number: TPS3820-50-Q1 Hi, team,
My customer met one question about TPS3820-50-Q1.
They use a switch to control the WDI and MCU connection, when in programming the switch is OFF, when in normal work the switch is ON. Thus when in programming, TPS3820…
Hi Team:
Just double confirm with you, if this part always no WDI signal. And the voltage is right. What the reset pin will be?
My understand is that, the reset will be like this.
On time is Ttout and off is Td. Right?
Deal all,
My customer has below questions about TPS3820-50-Q1. Could you help answer it? Thank you so much!
During WDI is high level , the N-MOS can not conduct fully, but work in the current limitation mode. You can refer the below pictures. So seems…
Other Parts Discussed in Thread: TPS3820 Anyone has the data of TPS3820-33-Q1 Watchdog time out for various operating temperature range? In datasheet, there is only 25°C watchdog time out. Thanks a lot!
Hi Aivaras,
Have you taken a look at one our watchdog supervisors such as the TPS3820-Q1 which has one output for both /RESET and WDO? This may be the solution you are looking for.
Thanks, Abhinav.
Shinji,
Does Vsense monitor only undervoltage? If so, I think TPS3851-Q1 is the correct device as this is undervoltage monitor with standard watchdog.. This will require external resistor divider on VDD because there is no fixed threshold for TPS3851…
Nicola,
There is no way to disable TPS3813-Q1 unfortunately. TPS3850, TPS3851 or TPS382x family (TPS3820, TPS3823, TPS3828, TPS3824) will work or the devices you mentioned in the app note will work.

Dear Michael,
Thank you very much for quick reply.
I'm sorry. I misstake tile. Device is TPS3820-33.
May I ask a question?
