Description and Introduction

Half Bridge Driver, Soft Turn-On, Single Input Plus Shut-Down, All high Voltage Pins on One Side, Programmable 0.5-5us Deadtime in a 14-pin DIP package The IR21094 is a high-voltage, high-speed power MOSFET and IGBT driver from International Rectifier (IR).  

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

### **Specifications:**  
- **High-Voltage Range:** Up to 600V  
- **Floating Channel Design** for bootstrap operation  
- **Gate Drive Supply Voltage (VBS):** 10V to 20V  
- **Output Current (Source/Sink):** 290mA / 600mA  
- **Under-Voltage Lockout (UVLO)** for both channels  
- **Matched Propagation Delay** for both channels  
- **Logic Input Compatibility:** 3.3V, 5V, and 15V

### **Descriptions and Features:**  
- Designed for driving **N-channel MOSFETs and IGBTs** in half-bridge configurations.  
- **Floating high-side driver** allows operation with bootstrap or isolated supplies.  
- **Integrated deadtime** prevents shoot-through in half-bridge applications.  
- **Low-side and high-side outputs** have independent inputs for flexible control.  
- **CMOS Schmitt-triggered inputs** with pull-down resistors for noise immunity.  
- **Wide logic supply range (5V to 20V)** for compatibility with various controllers.  
- **Robust protection** with under-voltage lockout (UVLO) on both channels.  

This driver is commonly used in **motor control, power supplies, and inverter applications**.

Alternative Part Number

  • FAN21094MX --: Half-bridge gate driver with similar high-side/low-side drive and bootstrap capability, pin-compatible in many designs.
  • L6387ED --: High-voltage half-bridge gate driver with comparable 600V rating and logic inputs, suitable functional replacement.
  • IRS21094PBF --: Same functional family from the original vendor's successor line, offering equivalent drive current and bootstrap operation.
  • L6384E --: High-voltage half-bridge gate driver with comparable drive current and bootstrap operation, suitable as a functional replacement with minor circuit review.
