UNISONIC TECHNOLOGIES CO., LTD M54123L LINEAR INTEGRATED CIRCUIT w w w . u n i s o n i c . c o m . t w 1 of 9 Copyright © 2009 Unisonic Technologies Co., Ltd QW-R122-001,D EARTH LEAKAGE CURRENT DETECTOR „ DESCRIPTION The UTC M54123L is a semiconductor integrated circuit with amplifier for a high-speed earth leakage circuit breaker. For the amplifying parts of eart h leakage circuit breaker, the UTC M54123L consists of differential amplifier, latch circuit and voltage regulator. In normal operating, the UTC M54123L 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 of latch circuit whose output is suitable for the characteristics of high- speed earth leakage circuit breaker. Until the input voltage reaches t he fixed level, latch circuit doesn’t become high. Then drives a thyristor which is connected to latch circuit’s output terminal. „ FEATURES * With good input sensitivity current temperature characteristics * High input sensitivity :VT=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 DIP-8 SOP-8 SIP-8 Lead-free: M54123LK Halogen-free:M54123LG „ ORDERING INFORMATION Ordering Number Normal Lead Free Plating Halogen Free Package Packing M54123L-S08-R M54123LK-S08-R M 54123LG-S08-R SOP-8 Tape Reel M54123L-D08-T M54123LK-D08-T M54123LG-D08-T DIP-8 Tube M54123L-G08-T M54123LK-G08-T M54123LG-G08-T SIP-8 Tube

When standard value of voltage (60Hz) between V R and V I is minimum, and output O S is low-level, or when standard value of voltage (60Hz) between V R and V I is maximum, and output O S is high-level, it is considered as a good one. 3. When standard value of voltage V SC(ON) is minimum, and output OS is low-level, or when standard value of voltage VSC(ON) is maximum, and output OS is high-level, it is considered as a good one. 4. Supply current 2 is neces sary to keep high in output OS. 5. After applying 30mV between V R and V I and shorting between them, it is considered as a good one if standard value of IGT flows out of output OS. 6. After supply voltag e applies 12V and output O S is high-level, it is considered as a good one in the standard value of supply voltage and in the low-level of output OS. 7.

Please connect C4 (>1μF) and C2 (<1μF). ZCT and load resistance RL of ZCT are connected between input pin 1 and 2. Protective resistance (RP=100Ω) must be insurted. RL and amplifier’s output (in Pin 4) regulates sensitivity current External capacitor C1 between pin 4 and GND is used for noise removal. Please connect a varistor or a diode (2 pcs.) to ZCT in parallel, because of when large current is grounded in the primary side (AC line) of ZCT, the following situation can be abandoned: The wave form in the secondary side of ZCT is distorted and some signals do not appear in the output of amplifier. Please connect capacitor (about 0.047μF) between pin 6 and pin 7.
