Part Number: TLIN1441-Q1

Hi

1. Can LIMP, nRST and WAKE pins be suspended without use?

2. WDT grounding, how long will the NWDR reset after the feeding stop?

3. Can the PIN/NCS PIN be directly grounded?

4. Is there any application hint for tlin1441-q1?

    Chen,

    Thank you for coming to us with these questions. Can you give any insight as to what kind of application the TLIN1441-Q1 is being used in?

    1. Yes this is okay. They can all be left floating.
    2. Are you referring to the pulse width of the nWDR pin when it's asserted? Minimum 2ms, typical 4ms, maximum 6ms.
    3. Yes it can if the device is meant to be used in PIN mode only.
    4. Yes, if you visit the technical documents section of the TLIN1441-Q1 product page on TI.com, under application notes there are write-ups about the watchdog use, LDO performance, and failsafe mode.

    Please let me know if you have any other questions.

    Regards,
