Analog Devices (ADI) has extended battery life with its latest battery management IC that improves charge and fuel gauge accuracy.

Analog Devices (ADI) announced today the availability of the MAX17330 battery management IC, which features an integrated fuel gauge and advanced battery protection features for single-cell lithium-ion and polymer batteries that extend battery runtime.

The MAX17330 provides longer run times than comparable products, monitors the self-discharge risk of battery cells within the solution, and reduces the solution size of single-cell battery-powered products.

By integrating battery charging, fuel gauge, protection, and authentication functions into a compact wafer-level package (WLP), the size is reduced by up to 36% compared to similar solutions.

ADI's proprietary AccuCharge and ModelGauge technologies increase charging accuracy by 20% and provide extremely safe discharge functions, making them suitable for medical and fitness wearables, home and building automation sensors, portable computers, and terminals.

The MAX17330 simplifies battery management for devices that use parallel cells, such as foldable smartphones and tablets, as well as AR/VR smart glasses.

Model Gauge M5 fuel gauge algorithm is adopted to improve the state of charge by more than 40% and the remaining gauge is accurate.The degree was raised.

The technology used in conventional battery charging ICs requires a margin of power for battery protection due to uneven charging, which limits the ability of the battery to be fully charged.

The latest commercial devices require multiple physically separate cells to distribute weight for ergonomic design and enhanced user experience.

Each battery has a different impedance, capacity, and initial state, which can make configuration difficult.

However, the MAX17330 solves this problem by using an integrated fuel gauge for each cell, providing accurate state-of-charge indication and eliminating the battery check process.
