Description and Introduction

HALF-BRIDGE DRIVER The IR21834PBF is a high and low side driver manufactured by Infineon Technologies. It is designed for use in half-bridge or full-bridge configurations in motor control, power supplies, and other high-voltage applications.  

### **Specifications:**  
- **Voltage Range:**  
  - High-side voltage: Up to 600V  
  - Logic input voltage: 3.3V, 5V, or 15V compatible  
- **Output Current:**  
  - Source: 290mA (typical)  
  - Sink: 600mA (typical)  
- **Propagation Delay:**  
  - 120ns (typical)  
- **Dead Time (Internal):**  
  - 540ns (typical)  
- **Operating Temperature Range:**  
  - -40°C to +125°C  
- **Package:**  
  - 8-lead PDIP  

### **Descriptions and Features:**  
- **Floating Channel Design:** Allows for bootstrap operation in high-side configurations.  
- **Undervoltage Lockout (UVLO):** Protects both high-side and low-side drivers.  
- **Matched Propagation Delay:** Ensures minimal delay between high and low side switching.  
- **Cross-Conduction Prevention:** Built-in dead time to prevent shoot-through.  
- **3.3V, 5V, and 15V Logic Input Compatibility:** Supports a wide range of control signals.  
- **High Noise Immunity:** Robust against voltage transients.  

This driver is commonly used in applications such as motor drives, inverters, and switch-mode power supplies.

Application Scenarios & Design Considerations

HALF-BRIDGE DRIVER

Alternative Part Number

  • FAN7384MX --: Half-bridge gate driver with similar high/low-side drive capability and 600V rating, pin-compatible alternative from a different series.
  • L6384E --: High-voltage half-bridge gate driver offering comparable drive current and bootstrap operation, suitable functional replacement.
  • IRS21834PBF --: Same functional family from Infineon's IRS series with equivalent 600V half-bridge driver specifications, though naming differs from the IR21834PBF source.
