Designers of lithium-ion (Li-ion) battery-powered mobile and portable devices like
wearables, electric bicycles, power tools and internet of things (IoT)
products can improve the end-user experience by extending run-time and
delivering the foremost accurate battery state-of-charge (SOC) data within the
industry with the MAX17262 single-cell and MAX17263 single-/multi-cell
fuel-gauge ICs from Maxim Integrated Products, Inc. (NASDAQ: MXIM). The
MAX17262 features just 5.2μA quiescent current, rock bottom level in its class, along side integrated current sensing. The MAX17263 features just 8.2μA quiescent current and drives 3-to-12 LEDs to point battery or system status, useful in rugged applications that don't feature a display.
Designers of electronic products powered by small Li-ion batteries struggle to increase device run-times to satisfy user expectations. Factors like cycling, aging and temperature can degrade Li-ion battery performance over time. Inaccurate SOC data from an unreliable fuel indicator forces the designer to extend the battery size or compromise the run-time by prematurely shutting the system down, albeit there's usable energy available. Such inaccuracies can contribute to a poor user experience thanks to abrupt shutdown or a rise in device charging frequency. Designers also strive to urge their products to plug quickly thanks to competitive demands. Maxim’s two new fuel-gauge ICs help designers meet end-user performance expectations and time-to-market challenges.
The MAX17262 and MAX17263 combine traditional coulomb counting with the novel ModelGauge™ m5 EZ algorithm for high-accuracy battery SOC without requiring battery characterization. With their low quiescent current, both fuel-gauge ICs minimize current consumption during long periods of device standby time, extending battery life within the process. Both even have a dynamic power feature that permits the very best possible system performance without draining the battery. within the MAX17262, an integrated RSENSE current resistor eliminates the necessity to use a bigger discrete part, simplifying and reducing the board design. within the MAX17263, the integrated, pushbutton LED controller further minimizes battery drain and alleviates the microcontroller from having to manage this function.
Key Advantages
High Accuracy: The ICs provide accurate time-to-empty, time-to-full, SOC (1 percent) and mAhr data across a good range of load conditions and temperatures, using the proven ModelGauge m5 algorithm
Fast Time to Market: The ModelGauge m5 EZ algorithm eliminates the time-consuming battery-characterization and calibration process
Extended Run-Time: Quiescent current of just 5.2μA for the MAX17262 and 15/8.2μA for MAX17263 extends run-time
Integration: Internal current-sense resistor (voltage and coulomb counting hybrid) in MAX17262 reduces overall footprint and BOM cost, eases board layout. It measures up to three .1A and is suitable for batteries of 100mAhr to 6Ahr capacity. For applications using higher currents or battery capacity outside this range, the MAX17263, or the MAX17260 released recently, are often used with an external current sense resistor of any size
Small size: At 1.5mm × 1.5mm IC size, the MAX17262 implementation is 30 percent smaller in size compared to employing a discrete sense resistor with an alternate fuel gauge; at 3mm × 3mm, MAX17263 is that the smallest in its class for lithium-ion-powered devices
LED Support: The single-/multi-cell MAX17263 also drives LEDs to point battery status on a pushbutton press or system status on system microcontroller commands
Commentary
“In a push to form their products more user friendly, consumer IoT device manufacturers search for solutions that are highly integrated to scale back design size,” said Raghu Raj Singh, lead semiconductor equipment analyst for Technavio. “Anything that extends the operating time of the device by minimizing battery drain are going to be viewed as a boon for these developers. Maxim’s fuel-gauge ICs are ideally suited to deal with both needs.”
“With these industry-leading ICs, Maxim solves many of the conflicting and difficult battery-management challenges faced by designers of portable products,” said Bakul Damle, director of business management, Mobile Solutions at Maxim Integrated. “Maxim fuel-gauge ICs empower design innovation that results in longer run-times for mobile and portable devices through industry-leading features and functionality.”
