FDA117GRTR

Isolators - Gate Drivers Overview

The FDA117GRTR is a photovoltaic MOSFET gate driver from Littelfuse, featuring an optically isolated input and output. It utilizes an internal LED coupled to a photodiode array to generate a floating power source for driving high-power MOSFETs. Key electrical parameters include a forward voltage of 1.4 V, a forward current of 1.5 mA, and an isolation voltage of 5000 Vrms. The device operates within a temperature range of -40°C to +85°C and offers a maximum turn-on delay time of 0.075 ms and a maximum turn-off delay time of 0.201 ms.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'G' or 'RTR' against the manufacturer's latest documentation to confirm packaging type (tube vs. tape and reel) and RoHS compliance status. Confirm end-of-life status as discontinuation notifications may affect long-term availability. Ensure the selected variant matches the required lead times and minimum order quantities specified by authorized distributors.

Isolators - Gate Drivers Selection Notes

Select this component when galvanic isolation is required between control logic and high-voltage power stages. The photovoltaic design eliminates the need for external bias supplies for the gate drive. Consider the 5000 Vrms isolation rating for safety-critical applications. Verify that the 1.5 mA forward current requirement aligns with the available drive capability of the upstream microcontroller or logic interface.
