FAN4146 — Ground Fault Interrupter

Features

Description

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.

For Two-Wire ALCI and RCD Applications

Precision Sense Amplifier and Bandgap Reference

Built-in AC Rectifier

Direct DC Coupled to Sense Coil

Built-in Noise Filter

Internally, the FAN4146 contains a diode rectifier,

precision bandgap 12V shunt regulator, precision low

V_OSoffset-sense amplifier, time delay noise filter,

window-detection comparators, and a SCR driver. With

Low-Voltage SCR Disable

SCR Gate Driver

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.

Adjustable Sensitivity

Minimum External Components

Meets UL 943B Requirements

Ideal for 120V or 220V Systems

Space-Saving SuperSOT™ 6-Pin Package

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_OSoffset-

sense amplifier allows direct coupling of the sense coil

to the amplifier’s feedback signal. This eliminates the

large 50/60Hz 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.

Applications

Personal Care Products

Two-Wire Electrical Outlets, Circuit Breakers, and

Power Cords Requiring GFI Safety Features

ALCI and RCCB Circuits

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.
