Description and Introduction

600V Single High Side Driver IC with propagation delay matched output channels in a 8-Lead SOIC package The IRS21851SPBF is a high-speed power MOSFET and IGBT driver manufactured by Infineon Technologies. Here are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Infineon Technologies  
- **Part Number:** IRS21851SPBF  
- **Type:** High- and Low-Side Driver  
- **Output Current (Source/Sink):** 2.0A / 2.0A  
- **Supply Voltage (VDD):** 10V to 20V  
- **Logic Input Voltage (VIN):** 3.3V, 5V, 15V compatible  
- **Propagation Delay (tP):** 120ns (typical)  
- **Dead Time (Programmable):** Yes  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**
The IRS21851SPBF is a high-performance gate driver IC designed for driving high-speed MOSFETs and IGBTs in half-bridge or full-bridge configurations. It features independent high- and low-side referenced output channels with matched propagation delays for precise control.  

### **Features:**
- **Floating Channel Design:** Allows driving high-side N-channel MOSFETs or IGBTs up to 600V.  
- **Compatible with 3.3V, 5V, and 15V Logic Inputs:** Ensures flexibility in interfacing with microcontrollers or DSPs.  
- **Programmable Dead Time:** Prevents shoot-through in half-bridge applications.  
- **UVLO (Under-Voltage Lockout):** Protects both high- and low-side drivers from insufficient supply voltage.  
- **Matched Propagation Delays:** Ensures accurate timing for synchronous switching.  
- **High Noise Immunity:** Robust design minimizes false triggering.  
- **Low Di/dt Gate Drive:** Reduces EMI and voltage spikes.  

This information is based solely on the manufacturer's datasheet and technical documentation.
