AUIRS2117S

Gate Driver Overview

The AUIRS2117S is an automotive-grade, single-channel high-side gate driver IC designed for driving power MOSFETs and IGBTs. It features a voltage rating of 600 V and operates with a supply voltage range of 10 V to 20 V. The device provides a peak source current of 0.29 A and a sink current of 0.6 A. Key electrical parameters include a turn-on propagation delay of 140 ns and a turn-off propagation delay of 140 ns. Undervoltage lockout thresholds are set at 8.2 V (Off) and 8.6 V (On) for both the bootstrap (VBS) and common (VCC) supplies. The component supports junction isolation and functions within an operating temperature range of -40°C to +125°C.

Gate Driver Procurement Notes

Verify that the specific order matches the AUIRS2117S part number to ensure automotive grade compliance. Confirm package type and marking codes align with Infineon specifications. Check for RoHS compliance status and lead time requirements directly with authorized distributors or the manufacturer. Ensure storage conditions meet semiconductor handling standards to prevent damage prior to assembly.

Gate Driver Selection Notes

Select this component when a single-channel high-side driver with automotive qualification is required. It is suitable for applications needing 600 V blocking capability and moderate drive currents. Consider the 140 ns propagation delays for timing-sensitive designs. Verify compatibility with the target MOSFET or IGBT gate charge requirements against the 0.29 A source and 0.6 A sink capabilities.

Gate Driver Part Context

The AUIRS2117S belongs to Infineon's EiceDRIVER family of isolated gate drivers. It utilizes proprietary HVIC and latch-immune CMOS technologies to provide ruggedized performance. This series is specifically engineered for high-voltage power switching applications, offering a compact solution for integrating control logic with high-power output stages in automotive and industrial sectors.

Gate Driver Replacement Considerations

The non-automotive equivalent IRS2117S shares similar electrical characteristics but lacks automotive qualification. Other variants in the series may offer different pinouts or additional channels. Always verify pin-to-pin compatibility and thermal performance before substituting.
