MITSUBISHI M54133FP/GP EARTH LEAKAGE CURRENT DETECTOR DESCRIPTION The M54133 is a semiconductor integrated circuit designed for high-speed type earth leakage breakers. This IC has built-in antilightning-surge function and anti-inverter-noise function. PIN CONFIGURATION (TOP VIEW) GND 1 IREF 2 16 VS 15 OPI+ M54133FP/GP FEATURES q Improvement of ability against unwanted tripping by lightning -surge. Adopt the two times counting system. Improvement of ability against needless action for lightningimpulse. q Improvement of ability against unwanted tripping by inverter -noise. Built-in operational amplifier (of low current dissipation) for active low-pass filter. Improvement of ability against needless action for high frequency and high harmonics. q Built-in delay time function An external capacitor is used to set the delay time. q High input sensitivity : VT=11.5mVrms Typ. q Low-current dissipation (at RIREF=180kΩ) In stand-by condition : IS=610µA Typ. q High stabilities design Adopt the circuits that is not affected by fluctuations of supply voltage/ambient temperature.
