### **Descriptions:**  
The MAX4173HESA+ is a precision, high-side current-sense amplifier designed for monitoring current in battery-powered systems, power supplies, and motor control applications. It provides a fixed gain (selectable by part number variant) and operates over a wide supply voltage range, making it suitable for automotive, industrial, and portable electronics.  

### **Features:**  
- **High-Side Current Sensing:** Eliminates the need for a low-side shunt resistor.  
- **Wide Input Common-Mode Range:** Supports operation from +4.5V to +28V.  
- **Low Quiescent Current:** 45µA (typical) for power-sensitive applications.  
- **Rail-to-Rail Output:** Ensures maximum dynamic range.  
- **Fixed Gain Options:** Available in 20V/V, 50V/V, and 100V/V.  
- **Small Footprint:** 8-pin SOIC package for space-constrained designs.  
- **High Accuracy:** ±1% maximum gain error for precise measurements.
