TPS25944A: TPS25944A Pspice model work as TPS25942A:

Part Number: TPS25944A

Hello,

I'm trying to simulate the following circuit and I'm expecting to see the current reach 1.2A for 4 ms then the the part should act as circuit breaker. 

As you can see from the simulation output the output current is limited to ILIM as specified in the TPS25942:

Datasheet reports:

The TPS25944 allows the overload current to flow through the device until I(LOAD) < I(FASTRIP). It starts the timer when I(LIM) < I(LOAD) < I(FASTRIP), and once the timer exceeds tCB(dly), the internal FET is turned off and FLT is asserted.

Could you tell me where is the mistake?

Thank you
