NCP302LSN27T1G

onsemi · Monitors & Reset Circuits · TSOP-5

NCP302LSN27T1G from onsemi, in a TSOP-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 that is active low for this NCP302LSN27 variant (CMOS complementary output), limited to −0.3 V to Vin + 0.3 V and 70 mA output current.
2 Input power_in Input power supply voltage (Vin) pin, rated at a maximum of 12 V.
3 N.C. unconnected No internal connection on the TSOP-5 pin connection diagram.
4 Ground power_in Ground reference pin for the device.
5 CD passive Delay capacitor pin, with voltage limited to −0.3 V to Vin + 0.3 V; it sets the reset time delay together with the internal pullup.
