3.1.1 Current Sense Resistor

The high-accuracy current-sense function is internally implemented, which allows a better real-time monitoring effect and more accurate diagnostics without further calibration. A current mirror is used to source 1 / KSNS of the load current, flowing out to the external resistor between the SNS pin and GND, and reflected as voltage on the SNS pin.

The HCXX-BASE-EVM resistor is located on pad R12. This resistor can be adjusted externally but do take into consideration temperature and supply voltage.
