This user manual describes the functions of a single cell Li-Ion battery fuel gauge technology using an MCU within the STM32 (ARM Cortex™-M3 core) family. The fuel gauge demonstration board is used to show the capability of an STM32 microcontroller to be used for battery fuel capacity monitoring.

The MAX17055G/MAX17055X evaluation kits (EV kits) are fully assembled and tested surface-mount PCBs that evaluate the stand-alone ModelGauge™ m5 host-side fuel gauge ICs for lithium-ion (Li+) batteries in handheld and portable equipment.

The MAX17201G/MAX17201X/MAX17211G/MAX17211X evaluation kits (EV kits) are fully assembled and tested surface-mount PCBs that evaluate the stand-alone ModelGauge™ m5 pack-side fuel-gauge ICs for lithium ion(Li+) batteries in handheld and portable equipment.

The MAX17260X evaluation kits are fully assembled and tested surface-mount PCBs that evaluate the stand-alone ModelGauge m5 host-side fuel-gauge ICs for lithium-ion (Li+) batteries in handheld and portable equipment.

Demonstration circuit 1894B is a daisy-chainable isoSPI battery-stack monitor featuring the LTC®6804-1.

The STEVAL-ISB017V1, STC3117 evaluation board, includes the STMicroelectronics OptimGauge™ algorithm. It provides accurate battery state-of-charge (SOC) monitoring, tracks battery parameter changes with operation conditions, temperature, and aging, and allows the application to get a battery state-of-health (SOH) indication. An alarm output signals low SOC or low voltage conditions and also indicates fault conditions like a missing or swapped battery.
