AUIRS2127S

Gate Driver Overview

The AUIRS2127S is a single-channel high-side gate driver IC designed for automotive applications, featuring integrated over-current protection and fault reporting. It supports IGBTs and N-channel MOSFETs with a voltage rating of 600 V. The device operates within a supply voltage range of 10 V to 20 V and delivers peak output currents of 290 mA (source) and 600 mA (sink). Key timing parameters include propagation delays of 150 ns, rise times of 80 ns, and fall times of 40 ns. It is qualified to AEC-Q100 standards and functions in temperatures from -40°C to +125°C.

Gate Driver Feature Summary

• Integrated over-current protection with active clamp and fault signal reporting
• High-voltage latch-immune CMOS technology for rugged operation
• Logic-compatible inputs suitable for standard microcontrollers
• Functional junction isolation for high dv/dt immunity

Gate Driver Applications

• Automotive powertrain inverters
• On-board charger (OBC) systems
• DC-DC converter high-side switching
• Electric vehicle traction motor drives

Gate Driver Procurement Notes

Verify the specific suffix against the official Infineon datasheet to confirm package type and tape/reel specifications. Ensure the component meets AEC-Q100 grade requirements for your target automotive application. Cross-reference the ordering part number with the manufacturer's current production status to avoid obsolete stock issues.

Gate Driver Selection Notes

Select this component when a single-channel high-side driver with built-in short-circuit protection is required. It is suitable for replacing legacy IRS2127 variants where automotive qualification is mandatory. Consider the SOIC-8 package constraints and thermal dissipation capabilities relative to the PCB layout design.

Gate Driver Part Context

This part belongs to the IR2127 family of high-voltage gate drivers. The 'AU' prefix denotes an automotive-grade version with enhanced reliability and qualification compared to industrial grades. It serves as a specialized solution for high-reliability power conversion stages in electric vehicles.

Gate Driver Replacement Considerations

The IRS2127S is a functional industrial equivalent but lacks automotive qualification. Verify pin compatibility and parameter margins before substitution. No direct drop-in automotive replacements are listed in public documentation.
