Isolated gate driver generates floating power source for standard MOSFETs and IGBTs
The optically isolated Littelfuse FDA117 gate driver provides a robust solution for power switches in solid-state relays, industrial control equipment and power supplies.
Littelfuse has announced the launch of the FDA117, an optically isolated photovoltaic gate driver which generates a floating power source, making it ideal for a wide range of isolated switching applications.
One of the key differentiators of the FDA117 is the ability to generate a floating power source with up to 15.3 V voltage and 60 µA current, making it suitable for directly driving standard MOSFETs and IGBTs, and securely turning them off in less than 0.5 ms.
Whether the gate driver is used in custom solid-state relay designs, for controlling electrical power and loads, or in industrial process control, the FDA117 provides the necessary isolation, rated at 5,000 Vrms, to protect equipment and individuals from electrical hazards.
The FDA117 is available in both 4-pin DIP through-hole and surface-mount packages, providing pin-out compatibility with other photovoltaic drivers on the market. This compatibility ensures ease of integration into existing designs without any substantial modifications.
