Description and Introduction

Half Bridge Driver, Soft Turn-On, Separate High and Low Side Inputs, Fixed 500ns Deadtime in a 8-lead SOIC package The IR2108S is a high-voltage, high-speed power MOSFET and IGBT driver manufactured by International Rectifier (IR), now part of Infineon Technologies.  

### **Specifications:**  
- **Manufacturer:** International Rectifier (NS)  
- **Output Configuration:** Half-Bridge  
- **Output Current (Source/Sink):** 210mA / 420mA  
- **Supply Voltage (Vcc):** 10V to 20V  
- **High-Side Voltage (Vbs):** Up to 600V  
- **Logic Input Voltage (VIN):** 3.3V, 5V, 15V compatible  
- **Propagation Delay:** 120ns (typical)  
- **Dead Time (Typical):** 540ns  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The IR2108S is designed to drive high-side and low-side N-channel MOSFETs or IGBTs in a half-bridge configuration. It features a high-voltage level-shifting circuit for the high-side driver, allowing it to operate with bootstrap or floating supplies.  

### **Features:**  
- **Floating Channel Design:** Enables high-side drive up to 600V  
- **Compatible with 3.3V, 5V, and 15V logic inputs**  
- **Matched Propagation Delay for Both Channels**  
- **Undervoltage Lockout (UVLO) for Both Channels**  
- **Cross-Conduction Prevention with Programmable Dead Time**  
- **Low Power Consumption**  
- **SOIC-8 Package for Compact Designs**  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to the official documentation.
