TPS3850-Q1: Disable watchdog lower boundary

Part Number: TPS3850-Q1
Other Parts Discussed in Thread: TPS3850, , TPS35, TPS36

Hi team,

I would like to know if I can disable lower boundary of watchdog timer in TPS3850 to use it as simple Time out type watchdog.

Is that possible?


  • Hello Shinji-san,

    TPS3850-Q1 does not support this feature.

    Also, does the customer want to change the type of watchdog on the fly using a pin or he wants to use window watchdog in one variant of application and time out watchdog in another.

    We are working on TPS35 and TPS36 family of supervisor + WD family device which offer pin compatible devices with time out and window watchdog devices respectively.

    Will this work?

    Thanks and Regards,


  • Hi Shridhar-san,

    Thank you. I just found this device and it looks it meets my requirement.
