This application note describes the various steps for implementing the MAX17301– MAX17303/MAX17311–MAX17313 1-cell ModelGauge m5 EZ fuel gauge with protector and SHA-256 authentication in a battery pack. The memory programming instructions describe how to load the fuel gauge and authentication information and lock it to prevent tampering with the authentication or fuel-gauge mechanisms.
This guide provides instructions for designing the PCB and programming the MAX17301-MAX17313 series ICs for use in battery packs. It covers proper circuit board layout to ensure measurement accuracy and ESD ruggedness, including specific recommendations for current sensing traces and component placement.

This guide provides instructions for designing the PCB and programming the MAX1730x/1x ICs for use in battery packs.
The CSP trace should travel directly from the pin to the sense resistor, and loop areas must be minimized.
