tps25944 application question?

Hi Sir

My customer want use TPS2594x in their product, due to they need breaker vin and vout when OCP and auto recover when OCP disapear.

so we promote TPS25944A to them.

Due to TPS25944 have no EVB, we use TPS25942 EVB, then we change TPS25944 ic to replace tps25942 ic.

but we found tps25944A  can't be recover after OCP.

may we need change any component in EVB, or some thing i miss?
