### **Descriptions and Features:**  
- Designed for driving high-speed MOSFETs and IGBTs in half-bridge configurations.  
- Integrated high-side and low-side gate drivers with independent inputs.  
- Matched propagation delays for both channels.  
- Floating high-side driver for bootstrap operation.  
- Protection against cross-conduction with programmable dead time.  
- CMOS Schmitt-triggered inputs for noise immunity.  
- Suitable for motor control, power supplies, and inverters.  

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

Application Scenarios & Design Considerations

HIGH AND LOW SIDE DRIVER

Alternative Part Number

  • FAN7392N --: High-side and low-side gate driver with similar 600V rating and pin-compatible DIP-14 package, suitable drop-in replacement for half-bridge driving.
  • L6388E --: High-voltage high and low side driver with comparable logic input and bootstrap operation, widely used alternative in motor and inverter designs.
  • IRS21814PBF --: Same functional family from Infineon with equivalent 600V half-bridge gate driver specifications and DIP-14 pinout.
