FAN73711MX

Gate Driver Overview

The FAN73711MX is a monolithic high-side gate driver IC designed for driving high-speed MOSFETs and IGBTs operating at voltages up to +600 V. It features a single channel with 4 A peak source and sink current capabilities, ensuring robust switching performance. The device operates within a supply voltage range of 10 V to 20 V and supports input logic levels of 0.8 V and 2.5 V. It utilizes an 8-SOIC surface-mount package and functions reliably across a temperature range of -40°C to 125°C.

Gate Driver Feature Summary

• High-voltage floating channel enabling bootstrap operation up to +600 V
• Integrated common-mode noise elimination circuit for stable high dv/dt environments
• Built-in shunt regulators on VDD and VBS pins for voltage stabilization
• Under-voltage lockout (UVLO) protection prevents malfunction during low supply conditions

Gate Driver Applications

• Plasma display panel maintenance and energy recovery circuits
• Motor drive converter switch drivers
• Switching power supply applications
• High-power DC-DC converter switch drivers

Gate Driver Procurement Notes

Verify the specific suffix 'MX' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the ordering information matches the required RoHS compliance status and material declaration requirements specified in the latest product change notices. Cross-reference the package dimensions with standard SOIC-8 specifications to guarantee PCB footprint compatibility.

Gate Driver Selection Notes

Select this component when a single-channel high-side driver is required for isolated gate control in high-voltage systems. The 4 A output current rating suits medium-power switching applications where fast transition times are critical. Consider the 8-pin SOP form factor for space-constrained designs. Verify that the input logic voltage levels align with the controlling microcontroller or DSP outputs before integration into the circuit design.
