January 3, 2013 - Operating at 23 µA, MAX17048 automatically detects when battery enters low-current state and switches into low-power 4 µA hibernate mode, while still providing accurate fuel gauging. ModelGauge™ algorithm provides state of charge and compensates for temperature and load variation. Available in 0.9 x 1.7 mm WLP and 2 x 2 mm TDFN packages, gauge is suitable for portable battery-powered applications, such as smartphones, wireless handsets, and mobile accessories.

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

SAN JOSE, Calif., -- 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(TM) 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.

Key Advantages

--  Accurate fuel gauging: ModelGauge algorithm provides accurate state of charge and compensates for temperature and load variation.
--  Simplified design: The algorithm also eliminates the need for the current-sense resistor required in competing coulomb-counting fuel gauges.
--  Power conservation: The MAX17048 automatically detects when the battery enters a low-current state and switches into a low-power 4uA hibernate mode, while still providing accurate fuel gauging. The IC automatically exits hibernate mode when the system returns to active state.
--  Upgrade path to full power management: The MAX17048 functionality is available in a Power SoC with identical IP to facilitate a complete power-management solution in a shortened time to market.

Industry Commentary

--  "Mobile device manufacturers are increasingly paying attention to enhancing user experience to set themselves apart from their competition," said Bakul Damle, Business Director at Maxim Integrated. "Having a simple but trustworthy fuel gauge to correctly inform the user about the battery status as well as improve runtime goes a long way in achieving this goal."
--  "Although fuel gauges have traditionally been found in notebook computer applications, they are increasingly appearing as a critical 'must-have' element in consumer devices. With a highly accurate fuel gauge, customers know how much battery is left in their mobile device and that gives them confidence in the product," said Susie Inouye, Principal Analyst of Databeans.

Availability and Pricing

--  The MAX17048 is available in an 8-bump WLP package (0.9mm x 1.7mm) and an 8-pin TDFN package (2mm x 2mm).
--  Pricing starts at $1.12 (1000-up, FOB USA).
