LN61CN1802MR-G

NATLINEAR · Monitors & Reset Circuits · SOT-23-3L

LN61CN1802MR-G from NATLINEAR, in a SOT-23-3L. 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 VOUT output Detection output; N-ch open drain for the LN61CN variant (needs external pull-up, output may be pulled up to max GND-0.3 to 8V), goes low (GND) when VIN is below detection voltage VDF.
2 GND power_in Ground pin.
3 VIN power_in Power supply input and monitored voltage, operating range 0.7V to 7V with absolute maximum 8V.
