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. After this initial test
cycle, the internal timer starts a test cycle every 90
minutes. During a test cycle, the FAN41501 simulates a
ground fault and monitors the key GFCI components. If
the FAN41501 detects a component fault, it verifies the
fault several times to prevent a false EOL signal. At no
time during a test cycle is the normal GFCI protection
disabled or compromised.
The FAN41501 includes a 5 V shunt regulator, one-
second timer, 90-minute timer, digital control logic,
detection comparators, and an EOL driver output.
The FAN41501, together with a GFCI controller such as
FAN4149, provides a complete UL943 GFCI function
with automatic monitoring capability, low system power,
and a minimum number of external components.
The 6-pin, SuperSOTpackage enables a low-cost,
compact design and layout.
