Description and Introduction

High and Low Side Driver, SoftTurn-On, Noninverting Inputs, Separate High and Low Side Inputs in a 8-pin DIP package The IR2181 is a high and low side driver IC manufactured by International Rectifier (IR).  

### **Specifications:**  
- **Voltage Range (VBS):** Up to 600V  
- **Output Current (Source/Sink):** 1.4A / 1.8A  
- **Supply Voltage (VCC):** 10V to 20V  
- **Propagation Delay:** 120ns (typical)  
- **Deadtime (Typical):** 540ns  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin DIP or SOIC  

### **Descriptions:**  
The IR2181 is a high-voltage, high-speed power MOSFET and IGBT driver with independent high and low side referenced output channels. It is designed for applications requiring high-side and low-side switching, such as motor drives, inverters, and power supplies.  

### **Features:**  
- **Floating Channel Design:** Allows for bootstrap operation for high-side drive.  
- **Cross-Conduction Prevention:** Built-in deadtime to prevent shoot-through.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Matched Propagation Delay:** Minimizes output distortion.  
- **CMOS/LSTTL Compatible Inputs:** Works with standard logic levels.  
- **High Noise Immunity:** Robust against switching noise.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official IR2181 datasheet.
