FAN7171MX-F085

Gate Driver Overview

The FAN7171MX-F085 is a high-side gate driver IC manufactured by onsemi, designed for driving IGBTs and N-channel MOSFETs. It operates within a supply voltage range of 10 V to 20 V and supports bootstrap voltages up to 600 V. The device features non-inverting logic inputs with thresholds of 0.8 V (VIL) and 2.5 V (VIH). It delivers peak output currents of 4 A for both sourcing and sinking. Typical switching times include a rise time of 25 ns and a fall time of 15 ns. The component is housed in an 8-SOIC package and is qualified under the AEC-Q100 standard for automotive applications.

Gate Driver Feature Summary

• High-voltage capability supporting bootstrap operation up to 600 V for high-side switching applications
• Automotive qualification compliant with AEC-Q100 standards for reliability in harsh environments
• Non-inverting input configuration simplifies control logic integration without additional inversion stages

Gate Driver Applications

• IGBT gate driving in industrial motor drives
• N-channel MOSFET control in automotive power systems
• High-side switching in DC-DC converter topologies

Gate Driver Procurement Notes

Verify the specific suffix F085 to confirm tape-and-reel packaging compliance. Ensure the procurement channel provides valid AEC-Q100 certification documentation. Check moisture sensitivity level (MSL 3) requirements for storage and handling procedures prior to assembly.

Gate Driver Selection Notes

Select this component when a single-channel high-side driver is required for voltages up to 600 V. The 4 A peak current capability suits moderate-power IGBT and MOSFET loads. Verify that the system logic levels align with the specified 0.8 V and 2.5 V input thresholds for reliable signal detection.

Gate Driver Part Context

This part belongs to the FAN7171 series of high-side gate drivers from onsemi. It is distinct from low-side or half-bridge variants such as the FAN3224 or FAN3228. The F085 suffix specifically denotes the reel packaging format used for automated surface-mount assembly processes.
