Description and Introduction

Dual Low Side Driver in a 8-lead SOIC package The IR4427STR is a dual low-side MOSFET driver manufactured by Infineon Technologies.  

### **Manufacturer Specifications:**  
- **Manufacturer:** Infineon Technologies  
- **Part Number:** IR4427STR  
- **Type:** Dual Low-Side MOSFET Driver  
- **Output Current (Source/Sink):** 1.4A / 1.8A  
- **Supply Voltage (VDD):** 10V to 20V  
- **Propagation Delay (Typical):** 55ns  
- **Rise/Fall Time (Typical):** 30ns / 20ns  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions and Features:**  
- **Dual Independent Channels:** Allows driving two separate MOSFETs.  
- **High-Speed Switching:** Optimized for fast switching applications.  
- **Under-Voltage Lockout (UVLO):** Protects against insufficient supply voltage.  
- **Matched Propagation Delays:** Ensures synchronized switching.  
- **CMOS/TTL Compatible Inputs:** Works with a wide range of logic levels.  
- **Low Power Consumption:** Suitable for energy-efficient designs.  
- **Shoot-Through Protection:** Prevents cross-conduction.  

This driver is commonly used in power management, motor control, and switching applications.
