Optically isolated photovoltaic driver provides floating power source
Littelfuse, Inc., an industrial technology manufacturing company empowering a sustainable, connected and safer world, announced the launch of the FDA117 Optically Isolated Photovoltaic Driver. This innovative product generates a floating power source, making it an exceptional choice for isolated switching applications in a wide range of industries. The FDA117 is specifically designed to control discrete standard power MOSFETs and IGBTs using a floating voltage source, ensuring isolation between the low-voltage drive input side and the high-voltage load output side. With an input control current range of 5 mA to 50 mA, an integrated fast turn-off circuitry, and 5 kVRMS reinforced isolation, the FDA117 provides sufficient voltage and current to drive discrete power MOSFETs and IGBTs effectively. One of the key differentiators of the FDA117 is its ability to generate a floating power source with up to 15.3 V voltage and 60 µA current, making it suitable for driving standard MOSFET devices and IGBTs.
