WEBENCH® Tools/TPS22990: tps22990

When the Vin & Bias are ready, the on pin have no any input power (no pull high & no pull low).

Is there any risk ?

    Hi Kent,

    The ON pin of the TPS22990 has no internal pull up or pull down circuitry. Therefore, if you apply VIN and VBIAS and leave the ON pin floating, then we cannot guarantee whether or not the device will be enabled or disabled. This will not damage the device, but it may lead to unwanted behavior in your system.

    Thanks,

    Alek Kaknevicius
