FDA215

Isolators - Gate Drivers Overview

The Littelfuse FDA215 is a dual photovoltaic MOSFET driver featuring optically coupled GaAlAs LEDs driving two photodiode arrays. It generates sufficient floating voltage and current to drive high-power MOSFET transistors directly. The device supports AC and DC switching configurations with a control current of 5 mA. It provides optical isolation between input and output, eliminating the need for external gate drive power supplies.

Isolators - Gate Drivers Feature Summary

• Dual channel photovoltaic isolation using GaAlAs LED and photodiode array technology
• Generates floating power source capable of driving high-power MOSFETs without external bias
• Configurable for both AC and DC switching applications
• Inherently free from EMI or RFI generation due to optical coupling

Isolators - Gate Drivers Applications

• Discrete solid state relay designs
• Isolated switching applications requiring high power MOSFET drive
• AC and DC signal switching circuits

Isolators - Gate Drivers Procurement Notes

Verify the specific manufacturer source, as the FDA215 part number appears in datasheets from Littelfuse, IXYS Corporation, and Clare, Inc. Ensure the component matches the required package type and electrical specifications for your design. Confirm availability through authorized distributors to guarantee authenticity and traceability.

Isolators - Gate Drivers Selection Notes

Select this component when isolated gate drive capability is required without external power supplies. It is suitable for applications demanding high sensitivity and low control current. Consider the dual-channel configuration if multiple isolated switches are needed within a single package footprint.

Isolators - Gate Drivers Part Context

The FDA215 belongs to the series of optically isolated photovoltaic drivers manufactured by Littelfuse. These devices integrate the optical transmitter and receiver on a single chip to provide robust galvanic isolation. The series is designed for reliable performance in industrial and commercial switching environments.

Isolators - Gate Drivers Replacement Considerations

Check datasheets for FDA215S variants from Clare, Inc. or IXYS Corporation for potential pin-compatible alternatives. Verify that any substitute maintains the same photovoltaic drive capability and optical isolation ratings.
