EARTH LEAKAGE CURRENT
DETECTOR
SOP-8
DESCRIPTION
LINEAR INTEGRATED CIRCUIT
The UTC
M54123L
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
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 the fixed level, latch circuit
doesn’t become high. Then drives a thyristor which is connected to
latch circuit’s output terminal. Once the trigger latch circuit, only the
power on again to reset.

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Current value between V
R
and IN, and between IN and V
R
is less than 1ms in the pulse width, and duty
cycle is less than 12%, In applying AC current continuously, it is 100 mA in the off-state.

Notes: 1. Typical values are at T
A
=25°C
2. 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 O
S
is low-level, or when standard value of
voltage V
SC(ON)
is maximum, and output O
S
is high-level, it is considered as a good one.
4. Supply current 2 is necessary to keep high in output O
S
.
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 O
S.
6. After supply voltage 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 O
S
.
7. Operating time is a time from applying fixed input till operating latch circuit in 0.047μF between O
D
and
GND.
