Diodes Incorporated · Supervisor And Reset ICs · SOT-23
APX803L-40SA-7 from Diodes Incorporated, 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 APX803L; the SOT23 pin assignment places GND on pin 1. |
| 2 | RESET | output | Open-drain active-low reset output; the datasheet gives VRESET of 0 V to 5.5 V recommended, -0.3 V to 6.0 V absolute maximum, and IO output current limited to 20 mA. |
| 3 | VCC | power_in | Operating voltage input; recommended supply range is 0.9 V to 5.5 V, with absolute maximum rating of -0.3 V to 6.0 V. |
