NCP803SN293T1G

onsemi · Supervisor And Reset ICs · SOT-23

NCP803SN293T1G from onsemi, in a SOT-23. 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 GND power_in Ground reference pin for the supply and the reset output.
2 RESET output Open-drain active-low reset output that stays low while VCC is below the reset voltage threshold and for a reset timeout period after VCC rises above the threshold, and is guaranteed valid down to VCC = 1.0 V.
3 VCC power_in Supply voltage input monitored by the device, with a 100 nF bypass capacitor recommended between VCC and GND; operating VCC range is 1.0 V to 5.5 V.
