Description and Introduction

Half Bridge Driver, Soft Turn-On, All High Voltage Pins on One Side, Separate High and Low Side Inputs, Programmable 0.5-5us Deadtime in a 14-lead SOIC package The IR21084STR is a high-voltage, high-speed power MOSFET and IGBT driver from Infineon Technologies. Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
Infineon Technologies  

### **Part Number:**  
IR21084STR  

### **Description:**  
The IR21084STR is a half-bridge driver IC designed to control high-side and low-side N-channel power MOSFETs or IGBTs in a half-bridge configuration. It features independent high- and low-side referenced output channels with a floating high-side driver for bootstrap operation.  

### **Key Features:**  
- **High Voltage Range:** Up to 600V  
- **Floating Channel Design:** Allows for bootstrap operation of the high-side driver  
- **Gate Drive Supply Voltage (VBS):** 10V to 20V  
- **Output Current Capability:**  
  - Source: +290mA  
  - Sink: -600mA  
- **Under-Voltage Lockout (UVLO) Protection:** For both high-side and low-side drivers  
- **Matched Propagation Delays:** Ensures minimal dead time requirements  
- **Logic Input Compatibility:** 3.3V, 5V, and 15V logic levels  
- **Operating Frequency:** Up to several hundred kHz  
- **Package:** SOIC-8  

### **Applications:**  
- Motor drives  
- Switch-mode power supplies (SMPS)  
- Half-bridge and full-bridge inverters  
- Class D audio amplifiers

Description and Introduction

Half Bridge Driver, Soft Turn-On, All High Voltage Pins on One Side, Separate High and Low Side Inputs, Programmable 0.5-5us Deadtime in a 14-lead SOIC package The IR21084STR is a high and low side driver manufactured by Infineon Technologies. Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
Infineon Technologies  

### **Part Number:**  
IR21084STR  

### **Description:**  
The IR21084STR 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 requiring high efficiency and reliability in power conversion systems.  

### **Key Features:**  
1. **Floating Channel Design** – Allows for bootstrap operation to drive high-side N-channel MOSFETs or IGBTs.  
2. **Wide Voltage Range** – High-side gate drive voltage up to 600V.  
3. **Logic Input Compatibility** – 3.3V, 5V, and 15V logic compatible inputs.  
4. **Matched Propagation Delay** – Minimizes dead time for improved efficiency.  
5. **Undervoltage Lockout (UVLO)** – Protects against insufficient gate drive voltage.  
6. **High Output Current** – Capable of sourcing/sinking up to 290mA/600mA.  
7. **Low Di/dt Gate Driver** – Reduces EMI and switching losses.  
8. **Operating Frequency** – Suitable for high-frequency switching applications.  
9. **Package Type** – SOIC-8 (Surface Mount).  

### **Applications:**  
- Motor drives  
- Switch-mode power supplies (SMPS)  
- DC-DC converters  
- Inverters  
- Industrial power systems  

This information is based on the manufacturer's datasheet and technical specifications. For detailed electrical characteristics and application notes, refer to the official Infineon documentation.
