NCV301LSN40T1G

onsemi · Supervisor And Reset ICs · SOT-23-5

NCV301LSN40T1G from onsemi, in a SOT-23-5. 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 Reset Output output Reset output of the NCP301 open-drain N-Channel type (active low for the LSN40 option); the maximum output voltage is −0.3 V to 12 V and the maximum output current is 70 mA.
2 Input power_in Input power supply voltage (Vin) monitored by the detector, with a maximum rating of 12 V and a stated operating voltage range of 0.8 V to 10 V.
3 N.C. unconnected Not connected; the datasheet lists this pin as N.C. in the pin connections.
4 Ground power_in Ground reference pin for the device.
5 N.C. unconnected Not connected; the datasheet lists this pin as N.C. in the pin connections.
