TIC12400-Q1: Reset of TIC12400

Hi,

Is it recommended to use a capacitor across the RESET pin of the TIC12400?

    Hello Hemanth,

    The RESET pin is an active high signal and should remain low during normal operation.  To help prevent noise or transient pulses from creating a reset event, you can use a capacitor that would absorb the energy of the pulse and have to charge to a level sufficient to cause a reset event. 

    There isn't a requirement or specific recommendation on whether you should or should not use a capacitor and therefore you are free to use one if you would like.  Using a capacitor should not be a problem either, but if it is connected to a GPIO pin on the MCU, there will be an increase in the time between the MCU initiating a reset event by toggling the GPIO pin and when the cap is charge sufficiently to create the actual TIC12400-Q1 reset event.

    Regards,
