Description and Introduction

Compact, Low-Cost 1S/2S Fuel Gauges The **MAX17040G+T** is a fuel gauge IC manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Manufacturer:**  
- **MAXIM (Maxim Integrated)**  

### **Specifications:**  
- **Function:** Fuel Gauge IC for single-cell Li+ batteries  
- **Battery Chemistry:** Lithium-Ion (Li+)  
- **Number of Cells:** 1  
- **Interface:** I²C (2-wire serial)  
- **Operating Voltage Range:** 3V to 4.5V  
- **Accuracy:** ±7.5mV (voltage measurement)  
- **Current Measurement:** Integrated sense resistor (external)  
- **Temperature Monitoring:** Supports external thermistor  
- **Package:** 8-pin TDFN (3mm × 3mm)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The **MAX17040G+T** is a compact fuel gauge IC designed for single-cell Li+ battery applications.  
- It provides accurate state-of-charge (SOC) estimation without requiring battery characterization.  
- Uses Maxim’s proprietary **ModelGauge™ algorithm** for SOC calculation.  
- Includes automatic compensation for battery aging, temperature, and discharge rate.  

### **Features:**  
- **No Battery Characterization Needed** – Works with most Li+ batteries.  
- **Low Power Consumption** – Ideal for portable devices.  
- **I²C Communication** – Allows host system to read SOC, voltage, and current.  
- **Small Footprint** – 8-pin TDFN package for space-constrained designs.  
- **Integrated Voltage and Current Measurement** – Supports external sense resistor.  
- **Thermistor Input** – Enables temperature monitoring for improved accuracy.
