Industry's Simplest Micropower Fuel Gauge from Maxim Integrated Reduces Quiescent Current by 4x and Size by 3x

Maxim's ModelGauge™ algorithm reduces design complexity and maximizes battery runtime.

SAN JOSE, Calif., Jan. 2, 2013 — (PRNewswire) — �Maxim Integrated Products, Inc. (NASDAQ: MXIM) today announced that it is sampling the MAX17048, the industry's simplest low-power fuel gauge for Lithium-ion (Li+) batteries. Operating at only 23uA, this battery fuel gauge uses 4x less power than competitive devices and even less in micropower hibernate mode, in which the fuel gauge continues to operate. It needs only one external capacitor, not the multiple external devices of competitive devices, so it simplifies design, shrinks solution size by 3x, and reduces costs. This fuel gauge is ideal for portable battery-powered applications where size, cost, and power are critical, such as smartphones, wireless handsets, and mobile accessories, including Bluetooth® headsets, portable speakers, fitness devices, and Wi-Fi® routers.

Traditional fuel gauge designs require multiple external components including current-sense resistors, which increase both bill of materials (BOM) cost and design complexity. Those fuel gauges also use coulomb counting, which can drift and affect the accuracy of the gauge over time. The MAX17048 features the proven ModelGauge™ algorithm and does not require coulomb counting to report accurate battery state-of-charge, thus extending runtime. The MAX17048 functionality is also integrated into the company's TINI® Power System-on-Chip (SoC) to make it easier to upgrade designs to more complex systems.
