'Model Gauge m5' eliminates the need to check battery status, helping with rapid product launches
Battery pack cloning prevention with industry-first integrated SHA-256 security certification

Maxim Integrated Products Korea (CEO Kim Hyun-sik) has launched the 'ModelGauge m5' portfolio, which allows for easy and safe measurement of the remaining battery pack capacity of mobile devices.

The Maxim Model Gauge m5 battery level meter (MAX17201/MAX17205, MAX17211/MAX17215) is the industry's first to integrate SHA-256 security authentication and combine it with a 160-bit secret key to prevent battery pack cloning.



Because battery voltage varies depending on temperature and load, measuring the remaining battery capacity is difficult, and precise calibration is required to eliminate the accumulated offset error of the coulomb counter. The Maxim ModelGauge m5 uses a sophisticated algorithm to accurately convert individual raw data measurements, such as battery voltage, current, and temperature, into State of Charge (SOC%), mAhr, time-to-empty, and time-to-full data during charging, allowing users to use the device more conveniently and for a longer period.

The ModelGauge m5's EZ Environment configuration eliminates unnecessary battery characterization and calibration processes, simplifying design and accelerating time-to-market. It accurately measures battery usage without a reset and allows checking battery capacity even when not in a fully charged, discharged, or standby state.

As battery packs age, their characteristics change and operating time shortens, requiring replacement every few years. However, the ModelGauge m5's powerful algorithm detects even minute changes in battery capacity to accurately predict battery life before capacity drops rapidly.

In addition, system designers can extend battery life and plan the optimal battery replacement time by adjusting charger parameters using the ModelGauge m5's unique 'Cycle+' life prediction information. The Maxim ModelGauge m5 is ideal for wearables, drones, tablets, smartphones, and Internet of Things (IoT) applications that operate on rechargeable batteries.

“Based on decades of experience in battery management and cryptographic design, Maxim provides world-class, accurate, and secure battery level measurement solutions to all customers, including large manufacturers, startups, and makers,” said Bakul Damre, Managing Director of Mobile Power at Maxim Integrated. “The Maxim ModelGauge m5 EZ portfolio allows designers to focus on their core tasks without worrying about battery level measurement.”

The Maxim ModelGauge m5 product is available in a 14-pin, TDFN package (3mm x 3mm). In the range of -40°C to +85°C, the MAX17201/MAX17211 operates at 9µA and the MAX17205/MAX17215 operates at 12µA low power. With evaluation kits (MAX17201GEVKIT, MAX17205GEVKIT, MAX17211GEVKIT, MAX17215GEVKIT), a Maxim 1-wire (MAX17211/MAX17215) or 2-wire I2C (MAX17201/MAX17205) interface is provided for use with data and control registers. Further information on the Maxim Model Gauge m5 portfolio is available on the Maxim website (MAX17201, MAX17205, MAX17211, MAX17215).
