Maxim Integrated Products made implementing pack-side battery gauges in portable devices easier and more secure with the ModelGauge m5 lineup of the MAX17201/MAX17205 and MAX17211/MAX17215.
Fuel gauging can be difficult because battery voltage varies with temperature and load, while coulomb counting requires sophisticated compensation to eliminate offset accumulation errors. Maxim’s ModelGauge m5 fuel gauges include a sophisticated algorithm that converts raw measurements such as battery voltage, current and temperature into accurate state-of-charge (SOC%), absolute capacity (mAhr), time-to-empty and time-to-full (while charging), all of which improve the user experience of the host device while enabling maximum run-time.
To ease the design process, the ModelGauge m5 EZ configuration eliminates the time- and resource-consuming characterisation process for a large number of battery types. In addition, these fuel gauges were the industry’s first to integrate SHA-256 for secure authentication to prevent battery clones.
Battery packs generally need to be replaced every few years – when batteries age, their characteristics change over time and no longer provide adequate run-time. The ModelGauge m5 algorithm detects the smallest changes in the capacity of the battery to more accurately predict how long the battery will last before the capacity degrades rapidly. With the Cycle+ age forecast information from these fuel gauges, system designers are able to adjust charger parameters to extend the battery life, or to plan a timely replacement of the battery.
