TPS3823: Auto-reset Oscillator tolerance

Part Number: TPS3823

Hello

 

I found  Auto-reset Oscillator in TPS3823 has keep pulsing ( continously) once in  1.6sec from your answer in another post.

 

Question:

Auto-rest oscillator pulsing once in 1.6sec is typ value, and can we think  0.9sec  min and 2.5sec max ?

and it  varies for each device ?

 

Best Regards

 

 

 

 

 

  • Kanji-san,

    You are correct. The tolerance on the watchdog timeout is provided in the datasheet. The minimum is 0.9 seconds. The typical value is 1.6 seconds. The maximum is 2.5 seconds. These values will be influenced mostly by temperature and voltage at VDD. Your pulse on WDI must occur within this value to prevent your device from resetting.
