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 mV_rms

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

•

Operating power supply voltage range: 7 to 12 V

Operating ambient temperature: –20 to 85°C
