onsemi · Supervisor And Reset ICs · SOT-23-3
NCV809SN293D2T1G from onsemi, in a SOT-23-3. 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 device (pin description table states only 'Ground'). |
| 2 | RESET | output | For the MAX809 (active-low) RESET output, the pin stays low while VCC is below the reset voltage threshold and for a reset timeout period (140-460 ms for this part's ordering entry... see review) after VCC rises above the reset threshold; the output is CMOS and is valid down to VCC = 1.0 V. |
| 3 | VCC | power_in | Supply voltage input; the absolute maximum rating for VCC to GND is -0.3 V to 6.0 V and the VCC range in the electrical characteristics is 1.2 V to 5.5 V for TA = -40 °C to +105 °C. |
