Description and Introduction

Low-Cost / SOT23 / Voltage-Output / High-Side Current-Sense Amplifier The MAX4173FESA is a high-side current-sense amplifier manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX4173FESA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Supply Voltage Range:** +2.7V to +28V  
- **Input Common-Mode Voltage Range:** +4V to +28V  
- **Gain Options:** Fixed (20V/V, 50V/V, 100V/V)  
- **Bandwidth:** 500kHz (typical)  
- **Quiescent Current:** 100µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Accuracy:** ±1.5% (maximum gain error)  

### **Description:**  
The MAX4173FESA is a precision, high-side current-sense amplifier designed for monitoring current in battery chargers, power supplies, and motor control applications. It provides an amplified output voltage proportional to the current flowing through an external sense resistor.  

### **Features:**  
- High-side current sensing  
- Wide supply voltage range (+2.7V to +28V)  
- Low quiescent current (100µA)  
- Fixed gain options (20V/V, 50V/V, 100V/V)  
- No external components required for basic operation  
- Rail-to-rail output swing  
- Low offset voltage (±500µV max)  
- Reverse battery protection
