Description and Introduction

Dual Low Side Driver, Half Inverting Input in a 8-lead SOIC package The IR4428S is a high-speed, dual MOSFET driver manufactured by International Rectifier (IR). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Supply Voltage (VDD):** 10V to 20V  
- **Output Current (Source/Sink):** 1.5A (peak)  
- **Propagation Delay (tP):** 80ns (typical)  
- **Rise/Fall Time (10% to 90%):** 30ns (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Input Logic Compatibility:** TTL/CMOS (3.3V to 20V)  
- **Output Voltage Swing:** Rail-to-rail  
- **Package Type:** 8-pin SOIC  

### **Description:**  
The IR4428S is designed to drive both high-side and low-side N-channel MOSFETs in half-bridge or full-bridge configurations. It features independent high and low-side referenced outputs with matched propagation delays for precise switching control.  

### **Features:**  
- **High-Speed Switching:** Optimized for fast transitions to minimize switching losses.  
- **Cross-Conduction Prevention:** Built-in dead-time control to prevent shoot-through.  
- **Wide Input Voltage Range:** Compatible with 3.3V to 20V logic inputs.  
- **Low Power Consumption:** CMOS input design for reduced power dissipation.  
- **Under-Voltage Lockout (UVLO):** Protects MOSFETs by disabling outputs if supply voltage is insufficient.  
- **Matched Propagation Delays:** Ensures synchronized switching for high-side and low-side MOSFETs.  

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