Diodes Incorporated · Supervisor And Reset ICs · SOT-23
APX809S00-40SA-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 device, as listed in the SOT23 (SA) pin descriptions. |
| 2 | RESET | output | Push-pull active-low reset output for the APX809S, asserted when VCC falls below the reset threshold and held for at least 240ms after VCC recovers; the datasheet gives VOL max 0.3 V at 1.2 mA sink and VOH min 0.8VCC at 500 µA source, with a -0.3 V to 6.0 V absolute maximum voltage rating. |
| 3 | VCC | power_in | Operating voltage input monitored against the reset threshold, with a recommended supply range of 1.0 V to 5.5 V and an absolute maximum of -0.3 V to 6.0 V. |
