Hi Gareth,

The TPS22811 will protect against output overcurrent conditions by actively limiting the current only during start-up. If you are concerned with an external device causing an overcurrent event after startup, this would not be sufficient.

For driving off board loads, I would recommend our high side switch portfolio: https://www.ti.com/power-management/power-switches/high-side-switches/products.html

These devices offer adjustable current limiting as well as highly accurate current sensing along with other features.

Best Regards,

Elizabeth
