Littelfuse's FDA117 optically isolated photovoltaic driver

Littelfuse, an industrial technology company, has announced the FDA117 optically isolated photovoltaic driver.

This innovative product generates a floating power supply, making it an ideal choice for isolated switching applications in a wide range of industries.

The FDA117 is specifically designed to drive standard discrete MOSFET and IGBT transistors using a floating voltage source, providing isolation between the low-voltage control input and the high-voltage output of the load. With a control input current range of 5mA to 50mA, built-in fast shutdown circuitry, and improved 5kVRMS isolation, the FDA117 provides sufficient voltage and current to effectively drive MOSFET and IGBT transistors.

A key feature of the FDA117 is its ability to generate a floating power supply with a maximum voltage of 15.3V and a maximum current of 60µA, making it suitable for driving standard MOSFET and IGBT devices. This feature provides greater flexibility in application development, allowing direct control of standard MOSFET/ IGBT devices and safely shutting down external power semiconductors in less than 0.5 milliseconds.

The FDA117 provides the isolation barrier needed to protect equipment and people from electric shock, whether it is used in custom solid state relay designs, for power and load control, or industrial process control.

The FDA117 is available in 4-pin through-hole or surface mount DIP packages, providing pin-to-pin compatibility with other PV drivers on the market. This compatibility facilitates integration into existing designs without major modifications.
