FAN4147 Datasheet | Fairchild Semiconductor

Features - For GFCI and RCD Applications - Precision Sense Amplifier and Bandgap Reference - Built-in AC Rectifier - Built-in Noise Filter - Low-Voltage SCR Disable - Direct DC Coupled to Sense Coil - SCR Gate Driver - Adjustable Sensitivity - 400A Quiescent Current - Minimum External ponents - Meets UL 943 Requirements - Ideal for 120V or 220V Systems - Space Saving Super SOT™ 6-Pin Package Applications - GFCI Output Receptacles - GFCI Circuit Breakers - Portable GFCI Cords Description The FAN4147 is a low-power Ground Fault Interrupter (GFI) controller for detecting hazardous current paths to ground and ground-to-neutral faults. The FAN4147 application circuit opens the load contacts before a harmful shock occurs. Internally, the FAN4147 contains a diode rectifier, precision bandgap 12V shunt regulator, precision low VOS offset-sense amplifier, time delay noise filter, window-detection parators, and an SCR driver. With a minimum number of external ponents, the FAN4147 detects and...
