LM1851 Datasheet Ground Fault Interrupter

Manufacturer: Unisonic Technologies

Overview: UTC LM1851 LINEAR INTEGRATED CIRCUIT GROUND FAULT INTERRUPTER.

General Description

The UTC LM1851 is designed to provide ground fault protection for AC power outlets in consumer and industrial environments.

Ground fault currents greater than a presentable threshold value will trigger an external SCR-driven circuit breaker to interrupt the AC line and remove the fault condition.

In addition to detection of conventional hot wire to ground faults, the neutral fault condition is also detected.

Key Features

  • include circuitry that rapidly resets the timing capacitor in the event that noise pulses introduce unwanted charging currents and a memory circuit that allows firing of even a sluggish breaker on either half-cycle of the line voltage when external full-wave rectification is used. DIP-8 SOP-8.
