GC54123P-A2

GoChip Elec Tech Shanghai · Leakage Protection ICs · SOP-8

GC54123P-A2 from GoChip Elec Tech Shanghai, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VR input Reference voltage input to differential amplifier with maximum pin currents of 250 µA (VR-IN) or 30 mA (VR-GND).
2 IN input Input signal from zero-current transformer with maximum pin currents of 250 µA (IN-VR) or 30 mA (IN-GND).
3 GND power_in Ground reference for the circuit.
4 OD output Differential amplifier output with typical currents of -12 to -30 µA at VOD=1.2V or 17 to 37 µA at VOD=0.8V.
5 SC input Latch circuit input with ON voltage range of 0.7 to 1.4V and typical input current of 5 µA.
6 NR input Noise suppression input pin, typically connected to capacitor network.
7 OS output Final logic output to SCR gate with output current of -100 µA at 25°C or -75 µA at 80°C (VOS=0.8V).
8 VS power_in Power supply voltage input with typical quiescent current of 400-580 µA at VS=12V and VR-Vi=30mV.
