Description and Introduction

HIGH AND LOW SIDE DRIVER The IRS2181PBF is a high-speed power MOSFET and IGBT driver manufactured by International Rectifier (IR).  

### **Specifications:**  
- **Output Current:** 2.0A (source/sink)  
- **Supply Voltage (VDD):** 10V to 20V  
- **Logic Input Voltage (VIN):** 3.3V, 5V, and 15V compatible  
- **Propagation Delay:** 90ns (typical)  
- **Rise/Fall Time:** 30ns (typical)  
- **Under-Voltage Lockout (UVLO):** Yes (for both high and low side)  
- **Dead Time:** 540ns (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Lead PDIP  

### **Descriptions:**  
- The IRS2181PBF is a high-voltage, high-speed driver designed for driving both high-side and low-side N-channel MOSFETs or IGBTs in a half-bridge configuration.  
- It features independent high and low side referenced output channels with a floating high-side driver for bootstrap operation.  
- The device includes built-in dead-time control to prevent shoot-through in half-bridge applications.  

### **Features:**  
- **Floating High-Side Driver:** Supports bootstrap operation up to 600V.  
- **CMOS Schmitt-Triggered Inputs:** Ensures noise immunity.  
- **Matched Propagation Delay:** Minimizes output distortion.  
- **Cross-Conduction Prevention:** Built-in dead-time control.  
- **Under-Voltage Lockout (UVLO):** Protects against insufficient gate drive voltage.  
- **Wide Logic Input Range:** Compatible with 3.3V, 5V, and 15V logic levels.  

This driver is commonly used in motor control, power supplies, and DC-DC converters.
