The FAN4149 is a low-power controller for detecting hazardous current paths to ground and ground-to-neutral faults. The FAN4149 application circuit opens the load contacts before a harmful shock occurs.The FAN4149, in combination with the FAN41501 auto-monitoring digital controller, meets the 2015 UL943 self-test requirements for permanently connected GFCI products. The FAN4149 detects and protects against a hot-wire-to-ground fault and a neutral-to-line/load short. The FAN41501 periodically monitors the FAN4149 and critical GFI components to comply with the 2015 UL943 requirements. The minimum number of components and the small 6-pin package allow for a dense, flexible, application solution. The FAN4149 contains a precision bandgap 14 V shunt regulator, precision low-VOS sense amplifier, time-delay noise filter, window-detection comparators, and an SCR driver. The shunt regulator operates with a low quiescent current, which allows for a high value, low-wattage series supply resistor. The internal temperature compensated shunt regulator, sense amplifier, and bias circuitry provide for precision ground-fault detection. This enables the use of larger component variations so that binning or trimming external components is not required. The typical 50 µV VOS sense amplifier offset allows for direct DC coupling of the sense coil. This eliminates the large AC-coupling capacitor. The internal delay filter rejects high-frequency noise spikes common with inductive loads. This decreases false nuisance tripping. The SCR driver provides increased current and temperature compensation to allow for a wider selection of external SCRs.The minimum number of external components and the 6-pin SOT23 package allow a low-cost, compact design and layout.
