TPS25947: Can I use two TPS25947 to protect circuit that has a positivve and negative rail?

Tool/software:

Hi,

I am thinking about using a TPS25947EVM board to protect a device that is powered by a +18 V and -18V supply. I am planning to use one TPS25947 for the positive rail and another for the negative rail.

I am wondering if it would work. Thanks!
