Jetson AGX Xavier VIN LOSS DETECTION

Hi , Base on Jetson Xavier Developer Kit Carrier Board design (P2822-B03) , At Vin Loss detection circuit page , We have some question is below

  1. Is there any definition of time on capacitor C76/C78 and capacitor C77 ??

  2. The reverse leakage current of BAT54CW (D1) is high. If there’s reverse current it could turn on the transistor Q26 , is it possible ?

  3. What is the purpose of capacitor C75 ?? extend discharge circuit of time ??

Hi, regarding the questions of discharge circuit design, please just follow the reference design as it is validated. We can’t support customer to change it since any other design on it is not validated.
