AUIRS2117STR

Gate Driver Overview

The AUIRS2117STR is an automotive-grade, single-channel high-side gate driver IC designed for driving power MOSFETs and IGBTs. It operates with a supply voltage range of 10 V to 20 V and supports a bus voltage up to 600 V. The device features junction isolation (JI) for functional level shifting. Key electrical parameters include a peak source output current of 290 mA and a sink output current of 0.6 A. Propagation delays are specified at 125 ns for turn-on and 105 ns for turn-off. It is housed in an 8-pin SOIC package.

Gate Driver Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 standards
• Single-channel high-side topology with junction isolation
• Integrated undervoltage lockout for both supply and bootstrap voltages

Gate Driver Applications

• Automotive motor control systems
• High-side switching applications in industrial environments
• Power management circuits requiring isolated gate drive

Gate Driver Procurement Notes

Verify the specific suffix STR indicates tape-and-reel packaging configuration. Confirm that the automotive grade designation aligns with required AEC-Q100 qualification levels for your target application. Ensure compatibility with the 8-pin SOIC footprint during PCB layout planning. Cross-reference the datasheet version to confirm current regulatory compliance status.

Gate Driver Selection Notes

Select this component when a single high-side driver with automotive qualification is required. The 600 V rating suits medium-voltage power stages. Compare against non-isolated alternatives if cost reduction is prioritized over functional safety. Consider the 290 mA source current limit for capacitive load requirements. Verify thermal performance within the SOIC package constraints.

Gate Driver Part Context

This part belongs to the IRS2117 family of single-channel gate drivers. The 'AU' prefix denotes automotive qualification, distinguishing it from the standard industrial IRS2117S variant. It serves as a specialized solution for harsh automotive environments where junction isolation provides necessary functional safety margins without external optocouplers.

Gate Driver Replacement Considerations

The IRS2117S is the industrial-grade equivalent with identical electrical specifications but lacks automotive certification. The IR2117 is the legacy non-automotive version. Substitution requires verification of quality grade requirements rather than electrical compatibility.
