ADN8831 output  voltage and current not as expected

I am using the ADN8831 to drive a TEC rated at 5V/1.5A. I have set the limits to these values on the appropriate pins. When I try the circuit I measure around 2V across the TEC supply output and around 0.5A. Also the LP/LN transistors are getting very hot. So I am not sure why the voltage and current is a lot lower then the limits, and also why the transistor is getting so hot. BTW I am using the same transistors as in the eval board. 

Thanks for any help.
