I'm trying to construct H-bridge using DRV8701 gate driver. This part expects you to attach low-side shunt resistor to measure current going through motor to limit your duty cycle if motor is stalled. In the example provided in datasheet they use 50mOhm shunt resistor with expected current chopping level of 3A. I want to set chopping level to 10A, so it seems that 50mOhm resistor is too big, then I have to dissipate 10100.05=5W continuously through that resistor in worst case scenario.

I'm going to use 1mOhm resistor instead. But then parts sensor will sense only 10A*0.001=0.01V voltage drop, so is it reliable enough to sense current using such small resistor?
