TPS386000: Suggestion for alternate IC

Part Number: TPS386000

Hi,

My application requires 4 channel voltage monitoring, preferably adjustable as in TPS386000. From the data sheet I understand that watchdog delay time is not programmable and is typically 612ms. My application requires a delay time of 30ms. Please suggest an IC that provides this capability as well. Separate supervisor and watchdog IC suggestions are also welcome. The voltage threshold accuracy is expected to be <=1%.

Regards,

Lakshmi

  • Lakshmi,

    I think we have a couple solutions that will work. I wanted to clarify, When you say "application requires a delay time of 30 ms" are you talking about how long after a missed WDI pulse before the RESET is triggered (and goes low) or are you talking about the time RESET remains low before it comes back high (back to normal condition)?

    I will make some solution suggestions when that delay is clarified. Thanks!
