APX803S-29SR-7 from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RESET | output | Active-low, open-drain reset output. Asserts low when VCC falls below VTH (2.93V typ for -29) and remains low for tDELAY (240ms typ) after VCC returns above threshold. Requires an external pull-up resistor. Sinks up to ~3.5mA at VOL = 0.4V; guaranteed valid logic low for VCC > 1V. |
| 2 | GND | power_in | Device ground reference. |
| 3 | VCC | power_in | Operating voltage input and monitored supply. Recommended operating range 1.0V to 5.5V (absolute max 6.0V). The reset threshold is sensed on this pin; internal supply current is ~10µA typical (15µA max) above threshold. |
