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)

   Leakage detection: 650 µA (typical)

• High-stability design

   Adopts a circuit with minimal characteristic fluctuation when changes occur in the power supply voltage or ambient temperature

Applications

• Earth leakage breaker

Recommended Operating Conditions
