FAN41501 — Ground Fault Interrupter Self-Test Digital Controller June 2014 FAN41501 Ground Fault Interrupter Self-Test Digital Controller Features  Meets 2015 UL943 Self-Test GFCI Requirement  Internal 1-Second and 90-Minute Self-Test Timers  Periodic Functional Testing for Key GFIC Components: GFCI Controller, Solenoid, Sense Transformer, and Silicon-Controlled Rectifier (SCR)  Periodic EOL Testing without Compromising Normal GFCI Protection  Built-in Noise Filters Reduce False EOL Signals  Automatic EOL Reset Capability  Easily Added to Existing GFCI Applications  Built-in 5 V Shunt Regulator  Energy-Saving System Solution  Minimum External Components  Space-Saving SuperSOT™ 6-Pin Package Applications  GFCI Output Receptacle  GFCI Circuit Breakers  Portable GFCI Cords Description The FAN41501 is a digital controller for periodic functional testing of key Ground Fault Circuit Interrupters (GFCI) components. In combination with an existing Fairchild GFI controller, it periodically tests for the functional operation of the GFCI controller, solenoid, sense transformer, SCR, and other discrete components without disrupting power to the load or compromising normal GFCI protection functionality. If the FAN41501 detects a faulty GFCI component, it generates an End-of-Life (EOL) fault signal that can be used to deny power and/or automatically reset after the denial of power. When the AC power is first applied, an internal timer starts a test cycle at one second. Af...
