**HX(hengjiaxing)** · Monitors & Reset Circuits · SOT-23

HX810S-2.93V 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 (芯片接地端). |
| 2 | RESET | output | Reset output: it is high when VCC is below the detection voltage Vth and low once VCC rises above Vth, with VOL at most 0.3 V and VOH at least 0.8VCC. |
| 3 | VCC | power_in | Supply input with an operating range of 1.0 V to 6.0 V and an absolute maximum of 6.5 V. |
