MAX17041X+

Overview

The MAX17041X+ is a fuel gauge IC designed for two-cell lithium-ion or lithium-polymer battery packs. It utilizes the ModelGauge m3 algorithm to estimate state of charge without external current sensing resistors. The device operates on a dual supply configuration with a minimum voltage of 4.5 V and a maximum of 18 V. It features an I2C interface for communication and supports a maximum power supply current of 10 uA. The component is available in a 9-WLP package measuring 1.26x1.26 mm. It functions within a temperature range of -20°C to +70°C.
