RV4145AMT

onsemi · Power Management Specialized - PMIC · SOIC-8

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.
