Implementing pack-side battery gauges in portable devices is now easier and more secure with the ModelGauge m5 portfolio of MAX17201/MAX17205 and MAX17211/MAX17215 from Maxim Integrated Products.
They 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). 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, ModelGauge m5 fuel gauges are the industry’s first to integrate SHA-256 for secure authentication to prevent battery clones.
