RV4145AMT from onsemi, in a SOIC-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 | VFB | input | Sense amplifier negative input; internal 10 kΩ resistor R1 connects it to pin 3 (VREF), and the RSENSE feedback resistor connects from pin 7 to this pin. |
| 2 | +Input | input | Sense amplifier positive input; internal 10 kΩ resistor R2 to pin 3, offset voltage ±3.0 mV max at 25°C. |
| 3 | VREF | power_out | Reference voltage output at ½ VS (12.5 V min, 13.0 V typ, 14.6 V max at 25°C) used as the artificial ground for the op amp. |
| 4 | GND | power_in | Ground. |
| 5 | SCR | output | Trigger output that fires the external SCR when a fault is detected (detector on 2.8 V typ, 1.5 V min at 25°C); internal 4.7 kΩ typ resistor R3 to GND. |
| 6 | +VS | power_in | Supply input for the RV4145A circuitry with 26 V typ (25.0 to 29.2 V) shunt regulator clamp, fed from the AC line through RLINE. |
| 7 | Op Amp Output | output | Sense amplifier output; the SCR trigger fires when it exceeds ±7.2 V typ relative to pin 3. |
| 8 | NC | unconnected | No connect. |
