TPS22860: Selection of pulldown resistor

Neeraj Rai
Prodigy 100 points
Part Number: TPS22860

The datasheet for TPS22860 says that I need to put a pull-down resistor at VON. How should I calculate the value of this pulldown resistor?

    Hi Neeraj,

    As long as the ON pin is pulled down and not left floating, a pull down resistance is not necessary. However, if the ON pin is left floating, then a resistance of even 100kΩ would work here.

    As I mentioned in your other post, have you taken a look at the TPS22917? It is a very low leakage load switch, but an internal pull down resistance is integrated into the ON pin of the device. On top of that, the performance of this switch is higher than the TPS22810.

    Thanks,
