Description and Introduction

High and Low Side Driver, SoftTurn-On, Noninverting Inputs, Separate High and Low Side Inputs, All High Voltage Pins On One Side, and SPLG The IRS21814 is a high-speed power MOSFET and IGBT driver manufactured by Infineon Technologies. Here are its key specifications, descriptions, and features:  

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

### **Specifications:**  
- **Output Current:** 4 A (source/sink)  
- **Supply Voltage (VCC):** 10 V to 20 V  
- **Logic Input Voltage (VIN):** 3.3 V, 5 V, and 15 V compatible  
- **Propagation Delay:** 120 ns (typical)  
- **Rise/Fall Time:** 35 ns (with 1.8 nF load)  
- **Dead Time:** 520 ns (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**  
- The IRS21814 is a high-voltage, high-speed gate driver IC designed for driving both MOSFETs and IGBTs in half-bridge configurations.  
- It features independent high- and low-side referenced output channels with a floating design for the high-side driver.  
- The device includes under-voltage lockout (UVLO) protection for both high- and low-side drivers.  

### **Features:**  
- **High Noise Immunity:** CMOS Schmitt-triggered inputs with pull-down resistors.  
- **Matched Propagation Delay:** Ensures minimal dead time for improved efficiency.  
- **Floating High-Side Driver:** Allows operation with bootstrap or isolated supplies.  
- **UVLO Protection:** Prevents malfunction at insufficient supply voltages.  
- **Cross-Conduction Prevention:** Internal dead time ensures no shoot-through.  
- **Wide Logic Compatibility:** Supports 3.3 V, 5 V, and 15 V input logic levels.
