MITSUBISHI <CONTROL / DRIVER IC>
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 anti-
lightning-surge function and anti-inverter-noise function.
FEATURES
q Improvement of ability against unwanted tripping by lightning
-surge.
•Adopt the two times counting system.
•Improvement of ability against needless action for lightning-
impulse.
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.
