HX809S-2.93V from HX hengjiaxing, 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 | GND | power_in | Chip ground reference. Connect to system ground (0V). |
| 2 | RESET | output | Active-low reset output. Asserts low when VCC falls below Vth (2.93V typ, ±2%) and remains asserted for the built-in reset delay (Trp ≈ 350ms typ, 100-600ms) after VCC recovers above Vth. VOL ≤ 0.3V at ISINK=1.2mA; VOH ≥ 0.8·VCC at ISOURCE=500µA. |
| 3 | VCC | power_in | Chip supply and monitored input voltage. Operating range 0.9V-6.0V; absolute maximum 6V. Typical quiescent current 2µA (max 4µA at VCC=5.5V, no load). Voltage is compared against the internal 2.93V reset threshold. |
