Description and Introduction

SELF-OSCILLATING HALF-BRIDGE DRIVER The IR2151PBF is a high-voltage, high-speed power MOSFET and IGBT driver with independent high- and low-side referenced output channels. It is manufactured by Infineon Technologies (formerly International Rectifier).  

### **Key Specifications:**  
- **Voltage Rating:**  
  - High-side floating supply voltage: 600V  
  - Logic supply voltage (VCC): 10V to 20V  
- **Output Current:**  
  - Peak output current: ±100mA (source/sink)  
- **Switching Speed:**  
  - Rise time (typical): 80ns  
  - Fall time (typical): 40ns  
- **Propagation Delay:**  
  - High-side to low-side: 120ns (typical)  
  - Low-side to high-side: 120ns (typical)  
- **Operating Frequency:** Up to several hundred kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin PDIP  

### **Descriptions and Features:**  
- **Independent High- and Low-Side Outputs:** Enables driving both high-side and low-side power switches (MOSFETs/IGBTs) in half-bridge or full-bridge configurations.  
- **Floating High-Side Driver:** Allows operation with bootstrap or isolated power supplies.  
- **Built-in Deadtime Control:** Prevents shoot-through in half-bridge applications.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation by disabling outputs if VCC is too low.  
- **CMOS/LSTTL Input Compatible:** Can be driven by logic-level signals.  
- **Matched Propagation Delays:** Minimizes timing mismatches between high- and low-side outputs.  

The IR2151PBF is commonly used in switch-mode power supplies, motor drives, and other high-voltage switching applications.
