HX810R-2.63V from HX(hengjiaxing), 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 | Chip ground terminal. |
| 2 | RESET | output | Reset output (active-high per the intro text: output goes high when VCC is below the detection voltage; VOL max 0.3V at ISINK=1.2mA, VOH min 0.8VCC at ISOURCE=150uA); abs max -0.3V to VCC+0.3V. |
| 3 | VCC | power_in | Chip supply input and monitored voltage; operating range 1.0V to 6.0V, absolute maximum 6.5V. |
