TPS3808: measurement of Shutdown time in am-5728

Part Number: TPS3808

Hi,

I want to measure the shutdown time in TI Sitra AM-5728 board for one of my application requirement. As i configured GPIO4_1 pin as interruptable pin and this pin will get interrupt from TPS3808 processor and transition happens from high to low but i want to know the time taken for transition from high to low(Shutdown time). 

Best Regards,

Swarna

  • Swarna,

    This information is provided in Table 7.6 Switching Characteristics of the datasheet. If the /RESET is triggered because of SENSE input, the /RESET high to low propagation delay is 20us. If the /RESET input is triggered from /MR, then the high to low delay is 150ns. These are typical values and can vary from device from device and also if there is any additional capacitance on the /RESET pin.

    Please let me know if you have any more questions. Thank you!
