TPS3808: extending delay time to 40s

Part Number: TPS3808

Tool/software:

Hi Team,

Could you please help to advise the query from customer as below? Thanks.


In the spec the maximum delay time is 10 s. Is there any concern from TI side if we enlarge the CT to get 40 s delay time?

 

Best regards,

Terry

  • Hi Terry, 

    Thanks for your question! 

    I don't recommend trying to get a delay more than 10 seconds. It's always better to use the device as in it's recommended condition that highlighted in the datasheet. And even if they increase the capacitor value, they may not get the 40 second delay. It may assert earlier than that depending on the UV events frequency. 

    If you need further assistance to meet their 40 second delay, could you please provide more information on why they need 40 seconds delay? This is pretty high and I just want to understand their use case to better assist you. 

    Hope this helps!

    Best,
