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.

In combination with an Periodic Functional Testing for Key GFIC existing Fairchild GFI controller, it periodically tests for Components: GFCI Controller, Solenoid, Sense the functional operation of the GFCI controller, solenoid, Transformer, and Silicon-Controlled Rectifier (SCR) sense transformer, SCR, and other discrete components without disrupting power to the load or Periodic EOL Testing without Compromising compromising normal GFCI protection functionality. If Normal GFCI Protection the FAN41501 detects a faulty GFCI component, it Built-in Noise Filters Reduce False EOL Signals generates an End-of-Life (EOL) fault signal that can be used to deny power and/or automatically reset after the Automatic EOL Reset Capability denial of power. Easily Added to Existing GFCI Applications When the AC power is first applied, an internal timer Built-in 5 V Shunt Regulator starts a test cycle at one second. After this initial test cycle, the internal timer starts a test cycle every 90 Energy-Saving System Solution minutes. During a test cycle, the FAN41501 simulates a Minimum External Components ground fault and monitors the key GFCI components. If the FAN41501 detects a component fault, it verifies the Space-Saving SuperSOT 6-Pin Package fault several times to prevent a false EOL signal. At no time during a test cycle is the normal GFCI protection disabled or compromised. Applications The FAN41501 includes a 5 V shunt regulator, one- second timer, 90-minute timer, digital control logic, GFCI Output Receptacle detection comparators, and an EOL driver output. GFCI Circuit Breakers The FAN41501, together with a GFCI controller such as Portable GFCI Cords FAN4149, provides a complete UL943 GFCI function with automatic monitoring capability, low system power, and a minimum number of external components. The 6-pin, SuperSOT package enables a low-cost, compact design and layout.
