Description and Introduction

Half Bridge Driver, Single Input, All High Voltage Pins On one Side, Fixed 520ns Deadtime in a 8-lead SOIC package The IR2105S is a high-voltage, high-speed power MOSFET and IGBT driver from Infineon Technologies. Here are the factual details about its manufacturer, specifications, descriptions, and features:

### **Manufacturer:**  
- **Infineon Technologies**  

### **Specifications:**  
- **Output Configuration:** Half-Bridge  
- **Input Voltage (VDD):** 10V to 20V  
- **Output Current (Source/Sink):** 210mA / 420mA  
- **Rise Time (Typical):** 120ns  
- **Fall Time (Typical):** 90ns  
- **Propagation Delay (Typical):** 520ns  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
- The IR2105S is a high-voltage driver designed for driving MOSFETs and IGBTs in half-bridge configurations.  
- It integrates a high-side and low-side driver with independent inputs for better control.  
- Features a floating channel for bootstrap operation, enabling high-side drive in bridge circuits.  

### **Features:**  
- **Floating Channel for Bootstrap Operation**  
- **Under-Voltage Lockout (UVLO) for Both Channels**  
- **Matched Propagation Delay for Both Channels**
