MAX17043G+T

Analog Devices
A widely used single-cell fuel-gauge IC that is common in portable designs and has broad community support.

Overview

The MAX17043G+T is a single-cell battery fuel-gauge IC from Analog Devices (Maxim). It estimates state-of-charge and reports battery information to a host microcontroller using a serial interface, making it well suited for compact battery-powered products. The device is widely used in portable designs and has broad community and reference-design support.

Why Choose This Part

The MAX17043G+T is compact and designed for low-power battery-powered designs, offering accurate state-of-charge reporting without large external components. Its serial interface makes it easy to integrate with most microcontrollers, and its broad adoption means there are reference designs and community examples to speed development.

Applications

Smartphones and handheld devices
Provides accurate state-of-charge reporting for single-cell Li-ion powered consumer products.
Wearables and IoT sensors
Low-power fuel-gauge functionality that helps extend runtime and manage battery charging in small form-factor devices.
Portable medical and instrumentation devices
Enables reliable battery monitoring and user-facing battery percentage reporting for safety- and uptime-critical equipment.
Battery-powered embedded systems
Integrates with microcontroller I2C interfaces for system-level power management and graceful shutdown logic.

Getting Started

Begin with the MAX17043 datasheet and any Analog Devices/Maxim application notes or evaluation kits for hardware reference. Connect the gauge to your MCU over the I2C/SMBus-compatible interface, power the cell, and read the SOC and voltage registers; many vendors and community repositories provide example drivers and initialization code. If you prefer a quick prototype, use a breakout board or an evaluation module that exposes the device pins and I2C lines.
