Preliminary
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: V_T=11.5mVrms Typ.
* Low-current dissipation (at R_IREF=180kΩ)
In stand-by condition: I_S=610μA Typ.
* High stabilities design
Adopt the circuits that is not affected by fluctuations of supply
voltage/ambient temperature.
