This document describes the startup sequence to configure and utilize the fuel gauge functions of MAX17055.
This document details the initialization and loading process for the MAX17055 fuel gauge. It outlines the power-up sequence required by a host controller to configure the device and read state of charge (SOC) and other information over a 2-wire bus system. The guide covers three specific configuration options: EZ Config, Custom Short INI, and Custom Full INI with an OCV table.
| Resolution (SOC) | 1/256% or 1% at bit D8 |
|---|---|
| Resolution (Voltage) | 0.078125mV or 1.25mV at bit D4 |
| Resolution (Temperature) | 256°C or 1°C at bit D8 |
The device should be initialized and loaded with a customized model and parameters at power up before the host system reads the state of charge.
You must read the 48 words of the model back from the device to verify if it was written correctly; if values do not match, the process must be repeated.
The reported state of charge is read from memory location Ox06.
