SCR Gate Driver
Adjustable Sensitivity
Minimum External Components
Meets UL 943B Requirements
Ideal for 120 V or 220 V Systems
Space-Saving SuperSOT? 6-Pin Package
The FAN4146 is a low-power controller for AC outlet
Appliance Leakage Circuit Interrupters (ALCI) and two-
wire Residual Current Devices (RCD). The FAN4146
detects hazardous grounding conditions and open
circuits the line before a harmful shock occurs.
Internally, the FAN4146 contains a diode rectifier,
precision bandgap 12 V shunt regulator, precision low
V OS offset-sense amplifier, time delay noise filter,
window-detection comparators, and a SCR driver. With
the addition of a minimum number of external
components, the FAN4146 detects and protects against
a hot-wire-to-ground fault. The minimum number of
components and the small SuperSOT? package allow
for a small-form-factor, low-cost application solution.
The FAN4146 circuitry has a built-in rectifier and shunt
regulator that operates with a low quiescent current.
This 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. The low V OS offset-
sense amplifier allows direct coupling of the sense coil
to the amplifier’s feedback signal. This eliminates the
large 50/60 Hz AC-coupling capacitor. The internal
delay filter rejects high-frequency noise spikes common
with inductive loads. This decreases false nuisance
tripping. The internal SCR driver is temperature
compensated and designed to satisfy the current
requirements for a wide selection of external SCRs.
The minimum number of external components and the
6-pin SuperSOT? package enable for a low-cost,
compact design and layout. The FAN4146ESX is an
enhanced temperature range device.
