Description and Introduction

Compact, Low-Cost 1S/2S Fuel Gauges The MAX17040G+U is a fuel-gauge IC manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX17040G+U  
- **Type:** Fuel-Gauge IC  
- **Package:** 8-pin μMAX  
- **Operating Voltage Range:** 2.5V to 4.5V  
- **Communication Interface:** I²C (2-wire serial interface)  
- **Accuracy:** ±7mV cell voltage measurement  
- **Temperature Range:** -40°C to +85°C  
- **Applications:** Single-cell Li+ battery packs  

### **Descriptions:**  
The MAX17040G+U is a compact, low-power fuel-gauge IC designed for single-cell lithium-ion (Li+) battery applications. It integrates a highly accurate voltage measurement system and uses Maxim’s proprietary ModelGauge algorithm to estimate battery state-of-charge (SOC) without requiring battery characterization.  

### **Features:**  
- **No Battery Characterization Required:** Uses ModelGauge algorithm for SOC estimation.  
- **Low Power Consumption:** Typically 15µA operating current.  
- **High Accuracy Voltage Measurement:** ±7mV accuracy.  
- **Automatic Sleep Mode:** Reduces power consumption when idle.  
- **Small Form Factor:** 8-pin μMAX package.  
- **I²C Interface:** Allows communication with a host microcontroller.  
- **Supports Multiple Battery Chemistries:** Compatible with various Li+ battery types.  
- **Integrated Temperature Compensation:** Improves SOC accuracy over temperature variations.  

This information is based solely on the manufacturer's datasheet and technical documentation.
