12.2.2 Inner Layer Layout and Routing Example

For both input sensing resistor and charging current sensing resistor, differential sensing and routing method are

suggested and highlighted in below figure. Use wide trace for gate drive traces, minimum 15 mil trace width.

Connect all analog grounds to a dedicated low-impedance copper plane, which is tied to the power ground

underneath the IC exposed pad. Suggest using dedicated COMP1, COMP2 analog ground traces shown in

below figure.
