Description and Introduction

Current Sensing IC in a 8-pin DIP package The IR2170 is a high-voltage, high-speed power MOSFET and IGBT driver with integrated current sensing. Here are the key specifications, descriptions, and features from the manufacturer (International Rectifier, now part of Infineon Technologies):  

### **Specifications:**  
- **Supply Voltage (VCC):** 10V to 20V  
- **Output Current (Source/Sink):** 0.25A / 0.5A  
- **Operating Frequency:** Up to 200kHz  
- **High-Side Floating Supply Voltage (VB):** Up to 600V  
- **Propagation Delay:** 150ns (typical)  
- **Undervoltage Lockout (UVLO):** Yes (for both high-side and low-side)  
- **Integrated Current Sensing:** Yes (via external shunt resistor)  
- **Isolation Voltage:** 600V (between high-side and low-side)  
- **Package:** 8-pin DIP or SOIC  

### **Descriptions:**  
- The IR2170 is designed for driving high-voltage power MOSFETs and IGBTs in half-bridge or full-bridge configurations.  
- It includes an integrated current sensing feature, eliminating the need for an external isolation amplifier.  
- The device provides high noise immunity and robust performance in motor control, inverters, and power supplies.  

### **Features:**  
- **Fully Integrated Current Sensing:** Eliminates need for optocouplers or Hall sensors.  
- **High-Side and Low-Side Gate Drivers:** Supports half-bridge applications.  
- **Fast Propagation Delay:** Ensures precise switching timing.  
- **Undervoltage Lockout (UVLO):** Protects against insufficient gate drive voltage.  
- **600V Isolation:** Safe operation in high-voltage applications.  
- **Compatible with 3.3V and 5V Logic Inputs:** Easy interfacing with microcontrollers.  

For detailed application notes and further technical data, refer to the official IR2170 datasheet from Infineon Technologies.
