FDA217S

Isolators - Gate Drivers Overview

The FDA217S is a dual photovoltaic MOSFET driver from Littelfuse, featuring two independent channels within an 8-pin DIP SMD package. Each channel comprises an input LED optically coupled to a photodiode array output. The device supports both AC and DC switching configurations with a specified control current of 5 mA. It provides optical isolation between input and output circuits without generating electromagnetic interference (EMI) or radio frequency interference (RFI). The component is designed for machine insertion and wave soldering processes.

Isolators - Gate Drivers Feature Summary

• Dual independent photovoltaic drivers with integrated LED and photodiode array coupling
• Capable of configuring for both AC and DC switching operations
• Operates with a standard 5 mA control current input
• Eliminates EMI and RFI generation during operation

Isolators - Gate Drivers Applications

• Optically isolated gate driving for power MOSFETs
• AC and DC signal switching circuits
• Electromagnetically sensitive control interfaces

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'S' indicates the surface mount DIP variant when sourcing. Confirm the manufacturer datasheet matches the required pinout and isolation specifications. Ensure the supplier provides official Littelfuse documentation rather than third-party summaries. Check for RoHS compliance status if required by your assembly standards. Validate that the package type aligns with your PCB footprint requirements before finalizing orders.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel galvanic isolation is required for MOSFET gate control. It is suitable for designs needing low control current drive capabilities. Consider its suitability for environments where EMI suppression is critical. Evaluate the 8-pin SMD package constraints against available board space. Ensure the application voltage levels remain within the photodiode array limits defined in the electrical characteristics table.

Isolators - Gate Drivers Part Context

This part belongs to the FDA217 series of optically isolated photovoltaic drivers manufactured by Littelfuse. The series focuses on providing reliable isolation for power switching applications. The FDA217S specifically denotes the surface mount version of the dual-channel driver. It complements Littelfuse's broader portfolio of circuit protection and power control solutions.

Isolators - Gate Drivers Replacement Considerations

Consult Littelfuse official cross-reference guides for verified substitutes. Do not assume generic photovoltaic drivers are compatible due to potential differences in isolation voltage or current transfer ratios. Verify pin compatibility and package dimensions before substituting.
