We are using S12ZVM based design for our boards for motor drive.
All reference designs have a 0E resistor between the S12Z HG/LG pin and the gate pin of the Mosfet. Is there any significance of the resistor at this point in the circuit? We had it but in our next design we are eliminating the 0E resistors as we are reducing the BOM. Refer R4 ad R11 in image below.
Further to this, There are 0E resistor between HS/LS and the high side / low side circuit. For LS, is there any need for the 0E resistor? Can we eliminate them? Refer R14 below.
For HS, the recommended design with RC filter has 0E to HS and a 'parallel' RC circuit. We have a 10E resistor between the HS Pin and HS circuit. This 10E is also part of the RC. Is there any need to have a parallel 0E resistor to HS pin or is it okay to share the 10E? Refer R7 below which in our design is 10E with a shunt capacitor.
