FAN7081CMX

Gate Driver Overview

The FAN7081CMX is a high-side gate driver IC designed for driving MOSFETs or IGBTs at voltages up to 600V. It features an inverting input configuration and operates within a supply voltage range of 5.5V to 20V. The device provides peak output currents of 500mA source and 250mA sink. Typical rise and fall times are 15ns and 10ns, respectively. It is housed in an 8-SOIC package and supports surface-mount installation. The component is rated for junction temperatures between -40°C and 150°C and holds AEC-Q100 automotive qualification.

Gate Driver Procurement Notes

Verify the specific suffix (e.g., _F085) against current manufacturer documentation, as Fairchild Semiconductor's operations have transitioned to onsemi. Confirm end-of-life status with authorized distributors, as this part may be discontinued. Ensure the selected variant matches the required packaging and temperature rating specifications for your design.

Gate Driver Selection Notes

Select this component when a single-channel high-side driver is required for voltages exceeding standard logic levels. The inverting input logic must align with the control signal polarity. Consider the 8-SOIC thermal performance and the 600V blocking capability relative to the target application's bus voltage requirements.

Gate Driver Part Context

This device belongs to the FAN708x series of high-side gate drivers from Fairchild Semiconductor (now onsemi). It is part of the PMIC category, specifically under half-bridge drivers. The series is engineered for robust performance in demanding power conversion environments requiring isolated or bootstrap-driven high-side switching.

Gate Driver Replacement Considerations

Check for direct pin-to-pin replacements within the updated onsemi portfolio. Verify if newer revisions retain the same SOIC-8 footprint and electrical characteristics. Consult official substitution guides for any functional changes in the successor components.
