M54133GP
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.
Key Features
- 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
