Description and Introduction

High and Low Side Driver, SoftTurn-On, Low Side Inverting Inputs, Separate High and Low Side Inputs, All High Voltage Pins On One Side, Separate Logic and Power Ground, Programmable Deadtime in a 14-lead SOIC package The IR21834S is a high-voltage, high-speed power MOSFET and IGBT driver manufactured by International Rectifier (IR). Here are the key specifications, descriptions, and features:

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

### **Key Specifications:**  
- **High and Low Side Driver:** Independent high-side and low-side referenced output channels.  
- **Floating Channel:** Designed for bootstrap operation, allowing high-side drive voltage up to 600V.  
- **Output Current:** 1.4A source / 1.8A sink (typical).  
- **Supply Voltage (VCC):** 10V to 20V.  
- **Logic Input Compatibility:** 3.3V, 5V, and 15V logic levels.  
- **Propagation Delay:** 120ns (typical).  
- **Deadtime (Cross-Conduction Prevention):** Programmable via external resistor.  
- **Operating Temperature Range:** -40°C to +125°C.  

### **Descriptions & Features:**  
- **Gate Drive Voltage Range:** 10V to 20V.  
- **Undervoltage Lockout (UVLO):** Protection for both high-side and low-side drivers.  
- **Matched Propagation Delay:** Minimizes deadtime for efficient switching.  
- **CMOS Schmitt-Triggered Inputs:** Improved noise immunity.  
- **Outputs in Phase with Inputs:** Non-inverting driver configuration.  
- **Package:** 8-lead SOIC (Small Outline Integrated Circuit).  

This driver is commonly used in motor control, half-bridge, and full-bridge applications requiring high-voltage switching.
