M54134

UNISONIC TECHNOLOGIES CO., LTD M54134 LINEAR INTEGRATED CIRCUIT EARTH LEAKAGE CURRENT DETECTOR  DESCRIPTION The UTC M54134 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 * Improvement of ability against unwanted tripping by lightning-surge and lightning impulse. Two times counting system adopted. * Improvement of ability against unwanted tripping by inverter-noise. Built-in operational amplifier (of low current dissipation) for active low-pass filter. Improved high-frequency, high harmonic superposition performance * Internal time delay function * An external capacitor is used to set the delay time. * High input sensitivity: VT=11.5mVrms Typ. * Low-current dissipation (at RIREF=180kΩ) In stand-by condition: IS=610μA Typ. * High stabilities design Adopt the circuits that is not affected by fluctuations of supply voltage/ambient temperature.  ORDERING INFORMATION Ordering Number Lead Free Halogen Free M54134L-S16-R M54134G-S16-R M54134L-S16N-R M54134G-S16N-R Package SOP-16 SOP-16N Packing Tape Reel Tape Reel  MARKING www.unisonic.com.tw Copyright © 2023 Unisonic Technologies Co., Ltd 1 of 7 QW-R122-011.E M54134  PIN CONFIGURATION LINEAR INTEGRATED CIRCUIT  PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 PIN NAME GND IREF VCC OFFC TRC1 TRC2 DLYC SCRT VREF ILKI OPAO C2 OPIC1 OPI+ VS DESCRIPTION Grounding ...
