Description and Introduction

Halogen Converter Control IC in a 8-lead PDIP package. Features Auto Resetting Short Circuit Protection, Auto Resetting Overload ... The IR2161 is a high-voltage, self-oscillating half-bridge driver IC manufactured by Infineon Technologies (formerly International Rectifier). Below are the key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Supply Voltage (VCC):** 10V to 20V  
- **High-Side Floating Supply Voltage (VB):** Up to 600V  
- **Output Current (Source/Sink):** 290mA / 600mA  
- **Operating Frequency Range:** 20kHz to 250kHz  
- **Dead Time (Typical):** 1.2µs (internal fixed)  
- **Undervoltage Lockout (UVLO):** 8.7V (turn-on), 7.7V (turn-off)  
- **Maximum Junction Temperature:** 150°C  
- **Package:** 8-pin PDIP and SOIC  

### **Descriptions:**  
- The IR2161 is designed for driving MOSFETs or IGBTs in half-bridge configurations.  
- It integrates a high-voltage level shifter, oscillator, dead-time control, and protection features.  
- Self-oscillating operation eliminates the need for an external PWM controller.  
- Suitable for applications like electronic ballasts, SMPS, and motor drives.  

### **Features:**  
- **Integrated Bootstrap Diode:** Simplifies high-side gate drive circuitry.  
- **Programmable Oscillator:** Frequency set via external RC components.  
- **Internal Dead-Time Control:** Prevents shoot-through in the half-bridge.  
- **Under-Voltage Lockout (UVLO):** Protects against low supply voltage.  
- **Fault Protection:** Includes overcurrent shutdown and thermal shutdown.  
- **Low Power Consumption:** Optimized for energy-efficient designs.

Description and Introduction

Halogen Converter Control IC in a 8-lead PDIP package. Features Auto Resetting Short Circuit Protection, Auto Resetting Overload ... The IR2161 is a high-voltage, high-speed power MOSFET and IGBT driver manufactured by International Rectifier (IRF). Here are the specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage (VCC):** 10V to 20V  
- **Output Current (Peak):** 1.0A (source), 1.4A (sink)  
- **Operating Frequency:** Up to 500kHz  
- **Propagation Delay:** 120ns (typical)  
- **Rise/Fall Time:** 50ns (typical)  
- **Input Logic Compatibility:** CMOS/TTL  
- **Under-Voltage Lockout (UVLO):** 8.7V (turn-on), 8.3V (turn-off)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin DIP or SOIC  

### **Descriptions:**
- The IR2161 is designed to drive high-side and low-side N-channel MOSFETs or IGBTs in half-bridge or full-bridge configurations.  
- It integrates a high-speed level shifter for high-side gate driving and includes dead-time control to prevent shoot-through.  
- Suitable for applications like motor drives, switch-mode power supplies (SMPS), and inverters.  

### **Features:**
- **Floating High-Side Driver:** Supports bootstrap operation for high-side drive.  
- **Matched Propagation Delays:** Ensures precise timing for switching applications.  
- **Dead-Time Control:** Prevents cross-conduction in half-bridge circuits.  
- **Low Power Consumption:** Optimized for efficiency.  
- **CMOS Schmitt-Trigger Inputs:** Ensures noise immunity.  
- **Under-Voltage Lockout (UVLO):** Protects against insufficient supply voltage.  
- **Cross-Conduction Prevention:** Built-in logic to avoid simultaneous high-side and low-side conduction.  

The IR2161 is a reliable driver for power switching applications requiring high efficiency and fast switching speeds.
