LINEAR INTEGRATED CIRCUIT

EARTH LEAKAGE CURRENT

DETECTOR



DESCRIPTION

DIP-8

The UTC M54223 is a semiconductor integrated circuit with

amplifier for a high-speed earth leakage circuit breaker.

For the amplifying parts of earth leakage circuit breaker, the

UTC M54223 consists of differential amplifier, latch circuit and

voltage regulator.

In normal operating, the UTC M54223 should be connected to

the secondary side of the ZCT (zero current transformers). Here

the ZCT detects leakage current different amplifiers’ both input.

Then the signals which have been amplified are integrated by

an external capacitor. The integrated signal connects to the input

terminal whose output is suitable for the characteristics of high-

speed earth leakage circuit breaker.

SOP-8

UTC M54223 have not the latch circuit. When the leakage

signal is released, the circuit is automatically reset.



FEATURES

* With good input sensitivity current temperature characteristics

* High input sensitivity :V_T=6.1mV (Typ.)

* Only need low external component count

* High noise and surge-proof

* Low power dissipation :P_D=5mW (Typ.)

* May be used both as 100V and 200V.

* Wide temperature range : from -20 °C to +80°C
