6 FAQs about [Lithium battery pack fuel gauge IC]
What is the MAX17261 Fuel Gauge IC?
The MAX17261 from Maxim is a low power fuel gauge IC that implements the Maxim ModelGauge™ m5 algorithm. It monitors multiple-series cell battery packs using an external resistor divider. The fuel gauge provides precision measurements of current, voltage, and temperature.
What is a battery fuel gauge?
Battery fuel gauges determine the amount of charge remaining in a secondary battery, and how much longer (under specific operating conditions) the battery can continue providing power. Such indication
How does a MAX17261 Multi-Cell Fuel Gauge work?
The MAX17261 Multi-Cell Fuel Gauge provides precision measurements of current, voltage, and temperature. The temperature of the battery pack is measured using an internal temperature sensor or external thermistor. A two-wire I 2 C interface is used to access data and control registers.
How accurate is a fuel gauge?
To achieve sufficient accuracy while a battery is in use, the model parameters must be calibrated constantly through a process called fuel-gauge "learning." In conjunction with coulomb counting, that approach yields fuel gauges accurate to within a few percent.
How does an IC monitor a battery pack?
An IC like the MAX17261 from Maxim Integrated monitors multiple-series cell battery packs using an external resistor divider. It provides precision measurements of current, voltage, and temperature. The temperature of the battery pack is measured using an internal temperature sensor or external thermistor.
What applications can I use a gauge for?
Texas Instruments offers battery fuel gauges for a wide range of applications, including smartphones, notebooks, power tools, vacuums, and energy storage systems (ESS). These gauges can be equipped with integrated protection or designed for higher voltage applications up to 15 cells in series.
