Description and Introduction

Half Bridge Driver, Separate High and Low Side Inputs, Inverting Low Side Input, Fixed 520ns Deadtime in a 8-Lead package The IRS2103 is a high-speed power MOSFET and IGBT driver manufactured by International Rectifier (IR). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

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

### **Specifications:**  
- **High and Low Side Driver:** Independent high- and low-side referenced output channels.  
- **Floating Channel Design:** Allows for bootstrap operation up to 600V.  
- **Gate Drive Supply Voltage Range:** 10V to 20V.  
- **Output Current Capability:** 290mA (source) / 600mA (sink).  
- **Propagation Delay:** 120ns (typical).  
- **Deadtime (Between High and Low Outputs):** 540ns (typical).  
- **Operating Frequency:** Up to 500kHz.  
- **Undervoltage Lockout (UVLO):** For both channels.  
- **CMOS Schmitt-Triggered Inputs:** With pull-down resistor.  
- **Matched Propagation Delay:** Between high- and low-side channels.  
- **Logic and Power Ground ±5V Offset:** For noise immunity.  

### **Descriptions:**  
- The IRS2103 is a high-voltage, high-speed power MOSFET and IGBT driver with independent high- and low-side referenced output channels.  
- It is designed for applications such as motor drives, power supplies, and inverters.  
- The floating channel allows for easy high-side driving in half-bridge or full-bridge configurations.  

### **Features:**  
- **600V Bootstrap Voltage Capability**  
- **Cross-Conduction Prevention**  
- **3.3V, 5V, and 15V Logic Input Compatible**  
- **Extended Temperature Range (-40°C to +125°C)**  
- **Diode for Bootstrap Supply**  
- **Low Power Dissipation**  
- **Pb-Free and RoHS Compliant**  

This information is based on the manufacturer's datasheet. For detailed application notes and exact performance characteristics, refer to the official IRS2103 datasheet from International Rectifier.

Application Scenarios & Design Considerations

Half Bridge Driver, Separate High and Low Side Inputs, Inverting Low Side Input, Fixed 520ns Deadtime in a 8-Lead package

Alternative Part Number

  • FAN7382MX --: High-side and low-side gate driver with similar 600V rating and logic input compatibility, widely available and pin-compatible in many designs.
  • L6384E --: Half-bridge gate driver with comparable drive capability and bootstrap operation, suitable drop-in for many IRS2103 applications.
  • IR2113 --: Same vendor family high/low-side driver with higher current capability and similar pinout, often used as a direct upgrade substitute.
  • FAN2103MX --: Half-bridge gate driver with similar high/low-side drive capability and pin-compatible function, widely available and cost effective.
