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 in many designs and widely available.
  • L6384ED --: High-voltage half-bridge gate driver with comparable drive current and bootstrap operation, suitable drop-in for many IRS21834 applications.
  • IR2104STRPBF --: Classic half-bridge gate driver from the same vendor family with similar logic input and 600V rating, easy substitution with minor layout checks.
