App note: How to achieve greater accuracy in battery capacity readings for portable designs

App note from Maxim Integrated on using fuel gauge IC to obtain accurate battery state of charge readings. Link here (PDF) Because a product’s runtime is limited by battery capacity, it’s critical to have a precise method for measuring the remaining battery capacity to avoid an unexpected shutdown. This application note describes an experiment for […]

App note: Li-ion battery and gauge introduction

Richtek app note for Li-ion battery definitions and gauge introduction. Link here SOC is defined as the status of available energy in the battery and usually expressed as percentages. Because the available energy change depends on different charging/discharging currents, temperatures and aging effects, the SOC could be defined more clearly as ASOC (Absolute State-Of-Charge) and […]

App note: Battery fuel gauge IC (LC709203F) for 1-Cell Lithium-ion (Li+)

Lithium-ion fuel gauge IC from ON Semiconductors. Link here (PDF) The LC709203F is an IC that measures the remaining power level of 1-cell lithium-ion (Li+) batteries used for portable equipment etc. This product reduces fuel gauge errors with a unique correction technology during measurement of battery temperature and voltage. This technology has inherently high precision […]
