漏電保護專用集成電路 【產品參數規格書】
■DESCRIPTION
The M54123 is a semiconductor integrated circuit with amplifier
for a high-speed earth leakage circuit breaker.
■FEATURES
Good temperature characteristics of input sensitivity current
High input sensitivity (VT=6.1mV Typ.)
Low external component count
High noise and surge-proof
Low power dissipation (Pd=5mW Typ.) and may be used both-
as 100V and 200V.
High mounting density by SIL package with 8 pins
Wide temperature range (TA=-20℃~+80℃)
■APPLICATION: High speed earth leakage circuit breaker
■FUNCTION
The M54123 circuit for the amplifying parts of earth leakage
circuit breaker consists of differential amplifier, latch circuit and
voltage regulator. It is connected to the secondary side of the zerocurrent
transformer (ZCT) which detects leakage current in the
both input of the differential amplifier. Signals amplified by
differential amplifier are integrated by an external capacitor, and
connects to the input terminal of latch circuit with output suitable for
the characteristics of high-speed earth leakage circuit breaker.
Latch circuit keeps low in the output till the input voltage reaches
the fixed level, and output becomes high when the leakage current
more than fixed flows. It drives a thyristor connected to the output
terminal of latch circuit.

■應用描述: 高速對地漏電保護器集成電路
■功能描述
漏電保護器專用集成電路M54123系列
用於漏電保護器的信號放大部份，
由差分放大器、門鎖電路、穩壓電路組合而成。
零電流互感器(ZCT)檢測漏電，次級輸出作為差分放大
器的輸入，差分放大器與一個外接電路之電視器接合以將
信號放大，並連接到門鎖電路的輸入端。
在輸入電壓達到額定值時，門鎖電路的輸出端一直保持
低電平；當漏電電流值大於額定值時，輸出端變高，以此
來觸發與門鎖電路相連接的可控硅開關元件。
