The MAX77818EWZ+T by Analog Devices Inc. is a high-performance 3A switching charger with an integrated ModelGauge m5 fuel gauge, designed for USB-powered portable devices. It features a smart power path supporting dual inputs with reverse blocking and USB On-the-Go (OTG) functionality. The charger operates at a high switching frequency with high efficiency, enabling low heat designs and small external components.
The ModelGauge m5 algorithm provides industry-leading fuel gauge accuracy by combining coulomb counter linearity with voltage-based fuel gauge stability, including temperature compensation. It offers accurate battery capacity (SOC) and time-to-empty readings without calibration. The device also includes two high voltage input LDOs and is programmable via an I2C serial interface.
This IC is housed in a space-saving 72-bump, 3.867mm x 3.608mm, 0.4mm pitch WLP package. It is suitable for applications such as industrial PCs, portable medical devices, wearables, smartwatches, handheld devices, wireless speakers, Bluetooth headsets, smart home automation sensors, and the Internet of Things (IoT).
Key electrical specifications include a maximum charge current of 3A, a supply voltage up to 5V, and support for 1-cell Lithium Ion/Polymer batteries. It offers fault protection against over current and over voltage. The operating temperature range is -40°C to 85°C.
