FAN73901M

Gate Driver Overview

The FAN73901M is a monolithic high- and low-side gate drive IC designed to drive high-speed MOSFETs and IGBTs operating up to +600 V. It features a full NMOS transistor buffer output stage for high pulse current driving capability and minimal shoot-through. The device supports bootstrap operation, includes an advanced input filter to prevent noise-induced short pulses, and offers UVLO protection. Logic inputs are compatible with 3.3 V and 5 V systems, and the logic ground (VSS) and power ground (COM) allow ±5 V offset.

• High-power DC-DC converters

Gate Driver Procurement Notes

Verify the specific suffix 'M' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the ordering part number matches the exact voltage rating and pin configuration required for your design. Cross-reference the RoHS status and lead-free designation with the latest component documentation before finalizing procurement orders.

Gate Driver Selection Notes

Select this component for applications requiring reliable half-bridge driving of high-voltage power switches. The integrated bootstrap support simplifies high-side driver implementation. Consider the ±5 V ground offset flexibility for noisy environments. Verify that the peak output current capabilities align with the gate charge requirements of the target MOSFET or IGBT to ensure adequate switching performance.

Gate Driver Part Context

The FAN73901M belongs to onsemi’s family of high-current, high-voltage gate drive integrated circuits. These devices are engineered for robust performance in demanding power conversion environments. The series typically includes variants like the FAN7390 and FAN7391, offering similar high-voltage floating channel capabilities but potentially differing in current drive strength or specific protection features.

Gate Driver Replacement Considerations

The FAN7390 and FAN7391 are related high-side/low-side gate drive ICs from the same manufacturer. Verify compatibility regarding current drive ratings, pinout configurations, and specific protection features before substituting.
