DRV8308: Reduce loss through sense resistor

Part Number:DRV8308

Hello, I really love the DRV8308 because of the commutation logic feature that it has. However I am worried about the amount of power lost through the sense resistor. The device starts limiting current at 0.25V across the sense resistor. This means the the power lost is equal to your limiting current x 0.25V. We want to limit current at 3A, meaning we will use ~70mOhm resistor and burn 750mW accross it. Is there any way to use a smaller resistor without losing the current limiting functionality of the chip? I am worried about applying an amplifier to sense resistor as the output voltage still needs to be very small.

Thanks,
