Fuel-Gauge ICs Target Mobile and Portable Devices

Maxim Integrated Products has announced the MAX17262 single-cell and MAX17263 single-/multi-cell fuel-gauge ICs. The MAX17262 features just 5.2 µA quiescent current, along with integrated current sensing. The MAX17263 features just 8.2 µA quiescent current and drives 3 to 12 LEDs to indicate battery or system status. Such LEDs are useful in rugged applications that do not feature a display.

According to the company, electronic products powered by small Li-ion batteries struggle to extend device run-times to meet user expectations. Factors such as cycling, aging and temperature can degrade Li-ion battery performance over time. Inaccurate state of charge (SOC) data from an unreliable fuel gauge forces the designer to increase the battery size or compromise the run-time by prematurely shutting the system down, even if there is usable energy available.
Such inaccuracies can contribute to a poor user experience due to abrupt shutdown or an increase in device charging frequency. Designers also strive to get their products to market quickly due 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 battery SOC accuracy without requiring battery characterization. With their low quiescent current, both fuel-gauge ICs prevent current loss during long periods of device standby time, extending battery life in the process.

Both also have a dynamic power feature that enables the highest possible system performance without crashing the battery. In the MAX17262, an integrated Rsense current resistor eliminates the need to use a larger discrete part, simplifying and reducing the board design. In the MAX17263, the integrated, push-button LED controller minimizes battery drain and alleviates the microcontroller from having to manage this function.

The ICs provide accurate time-to-empty (1%) and time-to-full SOC data across a wide range of load conditions and temperatures, using the proven ModelGauge m5 algorithm. The ModelGauge m5 EZ algorithm eliminates the time-consuming battery-characterization and calibration process. A quiescent current of just 5.2 µA for the MAX17262 and 15/8.2 µA for MAX17263 extends run-time, Rsense current resistor (voltage and coulomb counting hybrid) reduces overall footprint and BOM cost, eases board layout

At 1.5 mm × 1.5 mm IC size, the MAX17262 implementation is 30% smaller in size compared to using a discrete sense resistor with an alternate fuel gauge; at 3 mm × 3 mm, MAX17263 is the smallest in its class for lithium-ion-powered devices. The single-/multi-cell MAX17263 also drives LEDs to indicate battery status on a pushbutton press or system status on system microcontroller commands

The MAX17262 is available at Maxim’s website for $0.95 (1000 pieces, FOB USA); the MAX17263 is also on the site for $1.49 (1,000 pieces). Both parts are also available via select authorized distributors. The MAX17262XEVKIT# evaluation kit is available for $60; the MAX17263GEVKIT# is available for $60.

48 V ZVS Buck Regulator Gets BGA Option

Vicor now offers the PI354x-00-BGIZ as its latest addition to the company’s 48V Cool-Power ZVS Buck Regulator portfolio, offering a new BGA package option to the existing PI354x-00-LGIZ LGA series. PI354x Cool-Power ZVS Buck Regulator’s high performance ZVS topology enables 48V direct to PoL without sacrificing performance. With step-down regulation from a higher voltage source, engineers can deploy more efficient power distribution architectures, reduce I2R losses, and eliminate costly and inefficient intermediate conversion stages.

Operating from 36 VIN to 60 VIN, the PI354x regulates an output voltage ranging from 2.2 V to 14 V and delivers an output current delivery up to 10 A. Power delivery can be further increased by using single wire current sharing without any additional components. The PI354x series is designed for a wide range of applications leveraging higher voltage distribution, including: telecom, network infrastructure, data centers, industrial, battery and lighting applications.

When used in conjunction with the Vicor front-end products and factorized power products, the PI354x series enables a complete power chain from AC or HVDC (200 V+) source to PoL. The PI354x series expands and enhances the Vicor Power Component Design Methodology.
