Description and Introduction

Half Bridge Driver, Separate High and Low Side Inputs, Inverting Low Side Input, Fixed 520ns Deadtime in a 8-pin DIP package The IR2103 is a high-voltage, high-speed power MOSFET and IGBT driver from International Rectifier (IR). Here are the key specifications, descriptions, and features from the manufacturer:  

### **Manufacturer:** International Rectifier (IR)  

### **Description:**  
The IR2103 is a high-voltage, high-speed MOSFET/IGBT driver with independent high- and low-side referenced output channels. It is designed for applications requiring high efficiency and reliability in half-bridge or full-bridge configurations.  

### **Key Features:**  
1. **Floating Channel Design** – Allows for bootstrap operation for driving high-side N-channel MOSFETs or IGBTs.  
2. **Wide Supply Voltage Range** – High-side gate driver supply voltage up to 600V (IR2103).  
3. **Output Current Capability** – Peak output current of 210mA (source) and 420mA (sink).  
4. **High-Speed Switching** – Propagation delays matched for both channels (typ. 120ns).  
5. **Undervoltage Lockout (UVLO)** – Protection for both high-side and low-side drivers.  
6. **3.3V, 5V, and 15V Logic Compatible Inputs** – Supports a wide range of control signals.  
7. **Cross-Conduction Prevention** – Built-in deadtime to prevent shoot-through.  
8. **Operating Temperature Range** – -40°C to +125°C.  

### **Applications:**  
- Half-bridge and full-bridge motor drives  
- Switch-mode power supplies (SMPS)  
- DC-DC converters  
- Uninterruptible power supplies (UPS)  

### **Package Options:**  
- 8-lead PDIP (DIP-8)  
- 8-lead SOIC (SOIC-8)  

The IR2103 is a robust driver IC suitable for high-voltage power switching applications.
