Description and Introduction

High-Side Measurement Current Shunt Monitor The INA139 is a high-side current shunt monitor manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage Range:** 2.7V to 36V  
- **Common-Mode Voltage Range:** 0V to 36V (independent of supply voltage)  
- **Quiescent Current:** 60µA (typical)  
- **Bandwidth:** 500kHz (typical)  
- **Gain Accuracy:** ±1% (max)  
- **Output Voltage Swing:** Rail-to-Rail  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** SOT-23-5  

### **Description:**  
The INA139 is a precision current shunt monitor that measures voltage across a shunt resistor and provides a proportional output voltage. It is designed for high-side current sensing in applications such as power management, battery monitoring, and motor control. The device operates with a wide common-mode voltage range, making it suitable for various industrial and automotive systems.  

### **Features:**  
- **Wide Common-Mode Voltage Range (0V to 36V)**  
- **Low Quiescent Current (60µA typical)**  
- **High Accuracy (±1% max gain error)**  
- **Rail-to-Rail Output Swing**  
- **Small SOT-23-5 Package**  
- **Wide Supply Voltage Range (2.7V to 36V)**  
- **High Bandwidth (500kHz typical)**  
- **Low Input Bias Current (10nA max)**
