IR21368SPBF

Gate Driver Overview

The IR21368SPBF is a three-phase bridge driver IC designed for high-voltage power applications. It integrates six independent half-bridge drivers, comprising three high-side and three low-side outputs. The device supports IGBT and N-channel MOSFET gate driving with a supply voltage range of 10 V to 20 V. It features undervoltage lockout for all channels and cross-conduction prevention logic. The component utilizes proprietary HVIC technology for ruggedized monolithic construction and includes an over-current shutdown function that terminates all six outputs simultaneously.

Gate Driver Feature Summary

• Integrates three independent half-bridge drivers for three-phase inverter configurations
• Includes cross-conduction prevention logic to ensure safe switching operations
• Features over-current shutdown capability that disables all output channels upon fault detection
• Supports bootstrap operation with floating channel design for high-side drive

Gate Driver Applications

• Motor control systems
• General purpose inverters
• Micro and mini inverter drives
• Air conditioner and washing machine compressor drives

Gate Driver Procurement Notes

Verify the manufacturer marking on the package to confirm International Rectifier or Infineon origin, as the product line was acquired. Ensure the suffix 'SPBF' corresponds to the specific SOIC-28 lead-free tape and reel packaging configuration required for automated assembly processes. Cross-reference the date code against current production status to avoid obsolete stock.

Gate Driver Selection Notes

Select this component when a single IC solution is required to drive a complete three-phase bridge topology. It is suitable for designs needing matched propagation delays across all channels to minimize phase imbalance. Consider the 10 V to 20 V gate drive supply range and compatibility with 3.3 V logic inputs for microcontroller interfacing without additional level shifting circuitry.

Gate Driver Part Context

This part belongs to the IRS2136x family of high-speed power MOSFET and IGBT drivers. It shares architectural similarities with the IRS2136 and IRS21362 but differs in input phase relationships and specific feature sets. The IR21368SPBF specifically provides inverting high-side outputs, distinguishing it from non-inverting variants within the same product family.

Gate Driver Replacement Considerations

The IRS21368PBF serves as a direct functional equivalent within the same series. Verify pinout compatibility and electrical specifications before substitution. Other family members like the IRS21362 offer different input phase characteristics and should only be considered if the application allows for modified control logic.
