Can someone help me with this? I’m about to replace this chip that crapped its pants, but the problem is I don’t know what type of resistors that are on the board that are blown. I read the text and it looks like R820, which is 0.820 ohms. I can’t figure out whether it is a current sensing one or a normal resistor.

yes, according to datasheet the resistors are connected to pins 19,20,22 which are low side of each output stage (Nu,Nv,Nw). those are wider traces and pair of paralleled resistors are on each stage rather than single R3 as shown in previous post. so those are indeed 0.82Ohm resistors

Thanks I’d thought so it was
