SS54123H from orisilicon, 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 | IN1 | input | Non-inverting input of differential amplifier for zero-sequence current detection, connects to toroidal current transformer secondary. |
| 2 | IN2 | input | Inverting input of differential amplifier for zero-sequence current detection, connects to toroidal current transformer secondary. |
| 3 | GND | power_in | Chip ground and reference potential. |
| 4 | OA | output | Amplifier filter output pin providing amplified and band-pass filtered zero-sequence current signal. |
| 5 | DLY | input | Delay adjustment pin for external RC network configuration of leakage protection trigger delay. |
| 6 | OS | output | SCR trigger output providing 1.5V nominal drive to external thyristor for AC power disconnection upon leakage detection. |
| 7 | VS | power_in | Power supply pin accepting 1.5V regulated internal supply voltage. |
| 8 | NC | unconnected | No connection, floating pin. |
