DRV8847SEVM: Performing a 1A output at 50% duty cycle

Part Number:DRV8847SEVM

I Ti community,

I am currently using the DRV8847S EVM in order to drive a Peltier Cell ( so I drive it like a DC motor ) with 1A, so I'd like to use the DRV8847 at his full potential with a 2A output and 50% duty cycle on the H brigde, wich will leads to a constant 1A.

The problem is that I tried to supply the board with 5V, and I am not able to reach a 2A ouput. I first tried to use the 2 PIN interface with a PWM on IN1 and IN2 at GND, and I am able to see my current wich is shaped by the PWM, but I am not able to reach more than 1A, even if I connect all the jumpers of the Rsense resitors as you can see below.

I also tried to use the Parralle bridge interface as they proposed on the datasheet but I am not able to see any signals :

Any suggestions that might help me ?

Thanks,

Florent
