LINEAR INTEGRATED CIRCUIT
EARTH LEAKAGE CURRENT
DETECTOR
„
DESCRIPTION
The UTC M54133 is a semiconductor integrated circuit
developed for use in high-speed earth leakage breakers
incorporating functions to protect against voltage surges and
inverter noise.
„
FEATURES
* Improvement of ability against unwanted tripping by
lightning-surge and lightning impulse.
Two times counting system adopted.
* Improvement of ability against unwanted tripping by
inverter-noise.
Built-in operational amplifier (of low current dissipation) for active
low-pass filter.
Improved high-frequency, high harmonic superposition
performance
* Internal time delay function
* An external capacitor is used to set the delay time.
* High input sensitivity: VT=11.5mVrms Typ.
* Low-current dissipation (at RIREF=180kΩ)
In stand-by condition: IS=610μA Typ.
* High stabilities design
Adopt the circuits that is not affected by fluctuations of supply
voltage/ambient temperature.

DESCRIPTION
Grounding
Pin for connecting resistor that sets constant current for internal circuits; approx. 1.3 V.
Output pin of the internal constant-voltage circuit. Connect decoupling capacitor.
Leakage input signal does not continue.
Leakage is detected and SCR turn on.
In these cases, this IC will be restored to the initial condition after a predetermined time.
Connect capacitor that determines restore time.
Pin for connecting capacitor that integrates signal output from discriminator of
leak-signal input level.
Pin for connecting capacitor to eliminate noise.
Pin for connecting capacitor that sets delay time in case of using delay function.
Output pin for driving a SCR.
Pin for providing input reference level of leakage detection. About 2.4V appears.
Other input pin of leakage detection.
Output pin of operational amplifier.
Pin for connecting capacitor that prevents abnormal oscillations. Connect capacitor
across IC at pins 11 and 12.
Negative input pins of operational amplifier
Pin for connecting capacitor that prevents noise from causing malfunction. Connect
capacitors across IC at pins 13 and 14 and across IC at pins 15 and 14.
Positive input pins of operational amplifier
