Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

The FAN4147 application circuit opens the load contacts before a Built-in AC Rectifier harmful shock occurs. Built-in Noise Filter Internally, the FAN4147 contains a diode rectifier, Low-Voltage SCR Disable precision bandgap 12V shunt regulator, precision low- V offset-sense amplifier, time delay noise filter, OS Direct DC Coupled to Sense Coil window-detection comparators, and an SCR driver. With SCR Gate Driver a minimum number of external components, the FAN4147 detects and protects against a hot-wire-to- Adjustable Sensitivity ground fault and a neutral-line-to-neutral-load short. The 400A Quiescent Current minimal components and the small SuperSOT package allow for a small-form-factor, low-cost solution. Minimum External Components The FAN4147 circuitry has a built-in rectifier and shunt Meets UL 943 Requirements regulator that operates with a low quiescent current. Ideal for 120V or 220V Systems This allows for a high-value, low-wattage-series supply resistor. The internal temperature-compensated shunt Space Saving SuperSOT 6-Pin Package regulator, sense amplifier, and bias circuitry provide for precision ground-fault detection. The low-V offset- OS Applications sense amplifier allows direct coupling of the sense coil to the amplifiers feedback signal. This eliminates the GFCI Output Receptacles large 50/60Hz AC-coupling capacitor. The internal delay filter rejects high-frequency noise spikes common with GFCI Circuit Breakers inductive loads. This decreases false nuisance tripping. Portable GFCI Cords The internal SCR driver is temperature compensated and designed to satisfy the current requirements for a wide selection of external SCRs. The minimum number of external components and the 6-pin SuperSOT package enable a low-cost, compact design and layout.
