Description and Introduction

High and Low Side Driver, SoftTurn-On, Noninverting Inputs, Separate High and Low Side Inputs in a 8-Lead package The IRS2181 is a high-speed power MOSFET and IGBT driver manufactured by International Rectifier (IR). Here are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
- **International Rectifier (IR)**  

### **Specifications:**  
- **Output Current:** ±1.5A (source/sink)  
- **Supply Voltage (VCC):** 10V to 20V  
- **Logic Input Voltage (VIN):** 5V TTL/CMOS compatible  
- **Propagation Delay (tP):** 120ns (typical)  
- **Rise/Fall Time (tR/tF):** 80ns (typical)  
- **Dead Time (Internal):** 520ns (typical)  
- **Operating Frequency:** Up to 500kHz  
- **Output Configuration:** High and low side driver  
- **Undervoltage Lockout (UVLO):** Yes (for both high and low side)  
- **Isolation Voltage:** 600V (floating high side)  
- **Package Options:** 8-lead PDIP, SOIC  

### **Descriptions:**  
- The IRS2181 is a high-voltage, high-speed MOSFET and IGBT driver with independent high- and low-side referenced output channels.  
- It is designed for use in half-bridge or full-bridge inverter applications.  
- The device features a dead-time control to prevent shoot-through in power stages.  

### **Features:**  
- **Floating Channel Design:** Allows for bootstrap operation for high-side drive.  
- **CMOS Schmitt-Triggered Inputs:** Ensures high noise immunity.  
- **Matched Propagation Delay:** Minimizes dead time for improved efficiency.  
- **Cross-Conduction Prevention:** Internal dead-time control.  
- **Low Power Consumption:** Optimized for energy-efficient designs.  
- **Wide Operating Temperature Range:** -40°C to +125°C.  

This information is based solely on the manufacturer's datasheet and technical documentation.
