Description and Introduction

Dual Low Side Driver, Half Inverting Input in a 8-pin DIP package The part **IR4428** is a **dual MOSFET driver** manufactured by **International Rectifier (IOR)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** International Rectifier (IOR)  
- **Type:** Dual MOSFET Driver  
- **Output Current (Source/Sink):** 1.5A / 1.5A  
- **Supply Voltage (VDD):** 10V to 20V  
- **Logic Input Voltage (VIN):** 5V TTL/CMOS compatible  
- **Propagation Delay:** 120ns (typical)  
- **Rise/Fall Time:** 50ns (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**
- The **IR4428** is a high-speed, dual-channel MOSFET driver designed to drive both high-side and low-side N-channel MOSFETs in half-bridge or full-bridge configurations.  
- It features independent inputs for each driver, allowing flexible control of the output stages.  
- The device is optimized for fast switching applications, minimizing power losses in power MOSFETs.  

### **Features:**
- **High Peak Output Current:** 1.5A source/sink capability for fast switching.  
- **Wide Supply Voltage Range:** 10V to 20V for compatibility with various power systems.  
- **TTL/CMOS Compatible Inputs:** Ensures easy interfacing with logic circuits.  
- **Low Propagation Delay:** Enhances system efficiency in high-frequency applications.  
- **Matched Propagation Delays:** Ensures synchronized switching in bridge configurations.  
- **Under-Voltage Lockout (UVLO):** Protects against insufficient gate drive voltage.  
- **Cross-Conduction Prevention:** Prevents shoot-through in half-bridge applications.  

This information is based solely on the manufacturer's datasheet for the **IR4428** from **International Rectifier (IOR)**.
