Description

The M54128L/FP is a semiconductor integrated circuit having leakage detection and abnormal voltage detection

functions for high-speed earth leakage interruption, and was developed for use in earth leakage breakers.

Features

• Lightning surge protection

Two-count method adopted

Improved dead-time performance for lightning impulses

• IEC support: 1.5 count method switching

• High input impedance

Filter circuit can be configured using external capacitor, resistor

Improved high-frequency, high harmonic superposition performance

• High input sensitivity: VT=6.5 Vrms

• Abnormal voltage detection (N open) function

Neutral line open-phase protection in single-phase three-wire designs

Function halt control (circuit current reduction)

• Low-voltage operation 7 to 12 V (versus 12 to 20 V in previous series)

Standby: 820 µA standard (VS = 9 V, Ta = 25°C)

SCR on: 740 µA standard (VS = 9 V, Ta = 25°C)

• Highly stable design

Circuit designed for minimum characteristic fluctuation with changes in power supply voltage, ambient temperature

Applications

• Earth leakage breaker

Recommended Operating Conditions

• Power supply operating conditions: 7 to 12V

• operating temperature: –20 to85°C
