IR21844SPBF

Gate Driver Overview

The IR21844SPBF is a half-bridge gate driver IC designed for IGBT and MOSFET applications. It features a wide supply voltage range from 10 V to 20 V. The device provides two independent drivers with output currents of 1.4 A source and 2.3 A sink. Key timing parameters include a rise time of 40 ns and a fall time of 20 ns. It operates within a temperature range of -40°C to +125°C and is housed in a SOIC-14 surface-mount package.

Gate Driver Feature Summary

• Integrated high-side and low-side drivers for half-bridge topologies
• Synchronous operation with programmable dead-time control
• Under-voltage lockout protection for both supply rails

Gate Driver Applications

• Motor drive systems
• Industrial power supplies
• Inverter circuits

Gate Driver Procurement Notes

Verify the specific suffix 'SPBF' against official Infineon documentation to confirm the tape-and-reel packaging variant, as this affects handling and storage requirements. Confirm RoHS compliance status directly with the manufacturer's current datasheet revision. Check component lifecycle status, as availability may be restricted due to end-of-life designations.

Gate Driver Selection Notes

Select this component when a robust half-bridge solution with integrated dead-time management is required. Ensure the input logic levels match the CMOS or TTL standards supported by the driver. Verify that the SOIC-14 thermal performance meets the application's power dissipation needs under maximum operating conditions.

Gate Driver Part Context

This part belongs to the IR218xx series of high-voltage gate drivers. It shares functional similarities with other models like the IR2184 but differs in packaging and specific electrical characteristics. The SPBF suffix indicates a specific reel-based packaging format compared to tube-packaged variants.
