Part Number: TPS3431 Hi,
I have some questions would like to confirm with you.
1. Does the deice issue WD signal out (WDO_N) to MCU through GPIO pin?
2. Additionally, could you help explain ENOUT function ?
The spec shows that ENOUT could connect with…

There is a good new that we could DIN TI product!
The customer wants to find the watchdog with the same specifications as TPS3431 but conforms to the Automotive!
Part Number: TPS3431-Q1 Hello team,
Per FAQ on Qualification available on TI e2e, The Q100 product is qualified based on the temperature grade. The stressing for Q100 product is pre and post tested at room and hot temperature per the grade pre and post…
Part Number: TPS3431 Hi.
I think WDO will be asserted for Trst after the timeout.
Does entering WDI during Trst return to normal operation?
Does entering WDI after Trst return to normal operation?
Part Number: TPS3431-Q1 Hi team,
i would like to know,
when EN is pulled low, the watchdog timer is stopped or reset to 0?
when SET1 is pulled low, the watchdog timer is stopped or reset to 0?
when SET1 is pulled low, WDO will change to high impedance or…
Part Number: TPS3431 WDO is asserted (logic low) even after giving WDI pulses within timeout (1.6 sec) using GPIO pins of STM32.
It is also asserted while SET1 pin is forced low.
Please find attached schematic for my custom board and oscilloscope screenshot…
Part Number: TPS3431-Q1 Hi Sir,
I just need the tune CWD cap to achieve the tWD 30s.
I need the watchdog timer always on.
I don't need the ON/OFF function.
I don't need the ENOUT too.
Can you suggest more suitable part or TPS3431-Q1 is good enough…
Part Number: TPS3431-Q1 Hi,
There are some cases in my application that the driving circuit for EN pin will become floating when I expect the EN should be logic low.
From the datasheet, EN pin is internally pulled up to VDD. Besides, I have to minimum the…
