Litteluse FDA117 Photoisolated Photovoltaic Driver

　　Litteluse has launched the FDA117 photovoltaic isolation driver, which can generate a floating power supply and is an excellent choice for isolation switch applications in various industries. FDA117 is designed specifically for controlling 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, integrated fast shutdown circuit, and enhanced isolation of 5 kVRMS, FDA117 can provide sufficient voltage and current to effectively drive discrete power MOSFETs and IGBTs.

　　One of the main differences between FDA117 and other products is that it is a floating power supply capable of generating up to 15.3V voltage and 60 µ A current, suitable for driving standard MOSFET devices and IGBTs. This feature can improve the flexibility of application design, achieve direct driving of standard MOSFET/IGBT devices, and safely turn off external power semiconductors in less than 0.5 milliseconds.

　　The product designs that can benefit from FDA117 include power semiconductor applications in the following markets (to name a few):

　　● Industrial

　　● Energy

　　● Building automation

　　● Smart home

　　The main advantages of FDA117

　　Whether used for customizing solid-state relay designs, controlling power and loads, or for industrial process control, FDA117 can provide necessary isolation barriers to protect equipment and personnel from electrical hazards.

　　Mark P. Smith, Director of Integrated Circuit and Microcontroller Product Management, said, "In order to provide customers with greater flexibility in application design, we have developed FDA117. This adds a single channel version to the existing photovoltaic driver product portfolio. The combination of high open circuit voltage and short circuit current with 5 kVRMS enhanced isolation voltage can effectively expand design flexibility."

　　The FDA117 adopts a 4-pin DIP through-hole and surface mount package, which is compatible with other photovoltaic driver pins on the market. This compatibility ensures that no major modifications are required and can be easily integrated into existing designs.

　　The FDA117 photovoltaic isolation driver has the following main characteristics:

　　During operation, the input control current is as low as 5 mA

• 　　Capable of driving standard power MOSFETs and IGBTs
• 　　Provide floating output voltage ranging from 10.5V to 15.3V
• 　　Integrated fast turn off circuit for controlling switches
• 　　5.000 VRMS reinforced insulation to improve safety
• 　　4-pin surface mounting and through-hole packaging options
