FDA217STR

Isolators - Gate Drivers Overview

The Littelfuse FDA217STR is an optically isolated photovoltaic gate driver featuring dual independent floating outputs. It operates with a 5 mA control current and generates sufficient voltage and current to drive high-power MOSFET transistors. The device provides optical isolation between input and output, enabling AC and DC switching configurations without generating EMI or RFI. It is designed for machine insertion and supports parallel, series, or isolated output arrangements.

Isolators - Gate Drivers Feature Summary

• Dual independent floating outputs configurable for parallel, series, or isolated applications
• Optically isolated input-to-output design prevents electromagnetic interference generation
• Capable of driving high-power MOSFET transistors via photodiode array power generation
• Machine-insertable construction suitable for automated assembly processes

Isolators - Gate Drivers Applications

• Discrete solid state relay designs
• High-power MOSFET gate driving circuits
• AC and DC switching applications requiring galvanic isolation

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix STR against official Littelfuse documentation to confirm tape-and-reel packaging specifications. Ensure the component matches the required isolation voltage ratings for your circuit design. Cross-reference the datasheet revision date to confirm compliance with current manufacturing standards before procurement.

Isolators - Gate Drivers Selection Notes

Select this component when dual isolated outputs are required for driving separate high-power stages. The photovoltaic output eliminates the need for external auxiliary power supplies for the gate drivers. Consider the 5 mA control current requirement for interface compatibility with logic-level signals in industrial control systems.

Isolators - Gate Drivers Part Context

The FDA217STR belongs to the FDA217 series of optically isolated photovoltaic drivers manufactured by Littelfuse. This series is engineered for robust electrical isolation in power electronics. The STR suffix typically denotes a specific packaging variant optimized for surface-mount technology and automated placement equipment.

Isolators - Gate Drivers Replacement Considerations

The FDA117 is a documented single-channel alternative within the same product family. Verify if single-channel isolation suffices for the application. Confirm that the replacement maintains equivalent isolation voltage and output drive capabilities.
