1ED44171N01BXTSA1

Overview

The Infineon Technologies 1ED44171N01BXTSA1 is a single-channel low-side gate driver from the EiceDRIVER family, designed for driving power MOSFETs and IGBTs. It operates within a supply voltage range of 12.7 V to 20 V and features non-inverting logic configuration. The device utilizes CMOS Schmitt-triggered inputs compatible with 3.3 V, 5 V, and 15 V logic levels. Packaged in a compact SOT-23-5 surface-mount case, it supports an operating temperature range from -40 °C to +125 °C. Key functional attributes include integrated under-voltage lockout and a single pin dedicated to both fault output and enable functions.

Feature Summary

• CMOS Schmitt-triggered input stage ensures noise immunity and compatibility with standard logic families.
• Integrated under-voltage lockout protects the driver and load during insufficient supply conditions.
• Single-pin architecture combines fault reporting and enable control to minimize external component count.

Applications

• Power Factor Correction (PFC) stages
• Industrial motor drives
• Home appliance inverters

Procurement Notes

Verify the complete part number including the suffix XTSA1 to confirm the specific tape-and-reel packaging variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected package matches the PCB footprint requirements for the SOT-23-5 form factor. Cross-reference the datasheet revision date to ensure alignment with current design specifications.

Selection Notes

Select this component when a robust low-side driver with integrated fault handling is required for space-constrained designs. The single-pin fault/enable feature simplifies control board layout compared to multi-pin alternatives. Verify that the input logic voltage levels match the controlling microcontroller or FPGA outputs. Consider the thermal performance of the SOT-23-5 package relative to the expected switching frequency and load current.
