Hello, I use drv8303 with bldc motor and 3 shunts with 50A mosfet. OCP is triggered with 45A threshold. I see high currents during lowside mosfet commutation, mainly on one phase. WHen I modify motor phases connections, THe high currents occure on the New corresponding phase, as if it dépends on the motor inductance. I see high currents on the shunts and they propagate on GND and éven on Gate Mosfets . How can I reduce those short circuits during mosfet commutations?
Sincerely yours
