Semiment · Leakage Protection ICs · SOP-8
SL54123ADC-TR from Semiment, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN1 | input | Signal amplifier input 1, connected to the zero-sequence current transformer (ZCT) secondary. |
| 2 | IN2 | input | Signal amplifier input 2, connected to the zero-sequence current transformer (ZCT) secondary. |
| 3 | GND | power_in | Ground. |
| 4 | NC | unconnected | No connect pin. |
| 5 | OA | output | Amplifier output, with an external filter capacitor (330nF in the test circuit). |
| 6 | DLY | passive | Delay setting pin with an external filter capacitor (3.3nF in the test circuit); sources typically 50uA high current and 10uA low current. |
| 7 | OS | output | Output control pin driving the external thyristor (SCR) with a ~30ms (20-40ms) high-level pulse on trip. |
| 8 | VDD | power_in | Power supply pin; internally regulated supply voltage 4.8-5.4V (typ 5.2V), absolute maximum operating current 8mA. |
