The SEMIKRON SKHI22BR is a dual-channel hybrid IGBT gate driver IC engineered for demanding industrial power electronics applications. Designed to drive half-bridge or dual switch topologies, it delivers precise, isolated gate signals with fast propagation times and robust protection logic. The SKHI22BR integrates undervoltage lockout, short-circuit protection, and error feedback in a compact hybrid package, making it a reliable solution for high-frequency, high-power switching stages where gate drive integrity directly impacts system uptime and IGBT longevity.

The SKHI22BR sees widespread deployment in industrial AC drives, servo amplifiers, UPS systems, induction heating equipment, and traction inverters. Its dual-channel architecture simplifies half-bridge gate drive design in three-phase inverter stacks, and its fault output signaling integrates cleanly with DSP and microcontroller-based control boards. OEMs and MRO operations in material handling, renewable energy, rail traction, and heavy industrial machinery regularly specify this driver when upgrading or repairing SEMIKRON IGBT module-based power stages.

Key Features of the SKHI22BR:

• Dual-channel isolated gate drive output suitable for half-bridge and dual-switch IGBT topologies
• Integrated short-circuit protection with adjustable blanking time for robust IGBT desaturation detection
• Undervoltage lockout (UVLO) on both primary and secondary sides prevents false gate firing during supply transients
• Active error output signal enables direct fault handshaking with DSP, FPGA, or microcontroller control stages
• Hybrid IC construction provides high noise immunity and consistent switching performance across industrial temperature ranges
• Compatible with standard SEMIKRON IGBT module families, simplifying drop-in replacement in existing power stack designs

With SEMIKRON factory lead times on the SKHI22BR currently running at 99 weeks, procurement teams face serious exposure to line stoppages, failed warranty repairs, and project delays. For MRO buyers supporting installed drive and inverter fleets, waiting two years for a gate driver is not a viable option. ATI Accurate Technology specializes in sourcing exactly these kinds of constrained, long-lead, and obsolete power semiconductor components. Whether you need a single piece for an emergency repair or a blanket order to buffer your service inventory, ATI has the sourcing network and the stocking strategy to meet your requirements without the factory wait.

ATI Accurate Technology is headquartered in Palmetto, Florida and ships same-day on orders received before 5PM EST. Our team works directly with maintenance engineers and procurement professionals on SEMIKRON gate drivers, IGBT modules, thyristors, diodes, and rectifier assemblies — including obsolete and allocated parts.
