Description
The M54134FP/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
