Description and Introduction

Half Bridge Driver, HO In Phase with RT, Programmable Oscillating Frequency, 1.2us Deadtime in a 8-pin DIP package The IR2154 is a high-voltage, high-speed power MOSFET and IGBT driver with integrated oscillator, produced by Infineon Technologies (formerly International Rectifier).  

### **Manufacturer Specifications:**  
- **Manufacturer:** Infineon Technologies (IR)  
- **Type:** Self-oscillating half-bridge driver  
- **Operating Voltage (VCC):** 10V to 20V  
- **Output Current (Source/Sink):** 210mA / 420mA  
- **Frequency Range:** Adjustable via external RC components  
- **High-Side Floating Supply Voltage (VB):** Up to 600V  
- **Deadtime:** Fixed internal deadtime (typ. 1.2µs)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** PDIP-8, SOIC-8  

### **Descriptions and Features:**  
- **Integrated Oscillator:** Eliminates the need for an external PWM controller.  
- **High-Voltage Level Shifting:** Enables high-side MOSFET/IGBT driving.  
- **Under-Voltage Lockout (UVLO):** Protects against low supply voltage conditions.  
- **Cross-Conduction Prevention:** Fixed deadtime prevents shoot-through.  
- **Low Power Consumption:** CMOS input stage for minimal power draw.  
- **Applications:** Used in SMPS, electronic ballasts, motor drives, and half-bridge converters.  

The IR2154 is designed for driving both high-side and low-side N-channel power MOSFETs or IGBTs in half-bridge configurations. Its self-oscillating feature simplifies circuit design by integrating timing control.
