UCC27712-Q1: UCC27712-Q1 COM and system GND connection problem

Part Number: UCC27712-Q1


Now we are using UCC27712-Q1 for motor driver (three phase).

Refer to the recommended layout as follow: 

For three phase inverter application, three UCC27712-Q1 are used.

As the ground of MCU and the power of IGBT are common, based on layout above,

system ground and power ground cannot meet the single point grounding.

For this point, will there be a power current interference to the signal side.
