Description and Introduction

High and Low Side Driver, SoftTurn-On, Inverting Inputs, All High Voltage Pins on One Side, Separate Logic and Power Ground in a 14-pin DIP package The IR21074 is a high-voltage, high-speed power MOSFET and IGBT driver from Infineon Technologies. Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
Infineon Technologies  

### **Specifications:**  
- **Output Current:** 290mA (source) / 600mA (sink)  
- **Supply Voltage (VDD):** 10V to 20V  
- **Logic Input Voltage (VIN):** 3.3V, 5V, and 15V compatible  
- **High-Side Floating Supply Voltage (VB):** Up to 600V  
- **Output Rise/Fall Time (Typical):** 120ns / 90ns (with 1000pF load)  
- **Propagation Delay (Typical):** 120ns (matched between high and low side)  
- **Deadtime (Typical):** 540ns (internal)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-lead PDIP, SOIC  

### **Descriptions:**  
- The IR21074 is a high-voltage driver IC designed to control both high-side and low-side N-channel MOSFETs or IGBTs in half-bridge configurations.  
- It integrates a high-speed Schmitt-triggered input for noise immunity and a shutdown feature for protection.  
- The driver includes an undervoltage lockout (UVLO) for both high-side and low-side sections to prevent malfunction at low voltages.  

### **Features:**  
- **Floating High-Side Driver:** Allows operation with bootstrap or isolated supplies.  
- **Matched Propagation Delays:** Ensures precise timing in half-bridge applications.  
- **Internal Deadtime:** Prevents shoot-through in half-bridge configurations.  
- **3.3V, 5V, and 15V Logic Compatible Inputs:** Supports various control signals.  
- **Low Power Consumption:** Optimized for efficiency.  
- **Robust Protection:** UVLO for both high-side and low-side drivers.  

The IR21074 is commonly used in motor drives, power inverters, and switch-mode power supplies.
