Description
The M54133FP/GP 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
• Lightning surge protection
   Two-count method adopted
   Improved dead-time performance for lightning impulses
• Inverter support
   For active/low-pass filter use
   Internal op-amp (low current consumption)
   Improved high-frequency, high harmonic superposition performance
• Internal time delay function
   A time delay function can be configured
• High input sensitivity
   VT=11.5 mVrms
• Low current consumption
   Standby: 610 µA (typical)
