描述 Description

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.FEATURES
● Improvement of ability against unwanted tripping by lightning-surge.
  
• Adopt the two times counting system.
  
• Improvement of ability against needless action for lightning impulse.
● 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.
● Built-in delay time 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.APPLICATION
  Earth leakage breakerRECOMMENDED OPERATING CONDITIONS
Supply voltage range............................................................7 to 12V
Operating ambient temperature.....................................-20 to +85°C
