HX809R-2.63V from HX hengjiaxing HX809R 2 63V, in a SOT-23-3. 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 / negative supply return. Connect to system ground. |
| 2 | RESET | output | Reset output. Active-low: pulled low when VCC falls below Vth (2.63 V typ. for HX809R) and released ~350 ms (typ.) after VCC returns above threshold. VOL ≤ 0.3 V at ISINK = 1.2 mA (VCC = Vth_min); VOH ≥ 0.8·VCC at ISOURCE = 500 uA (VCC > Vth_max). Absolute max output current 20 mA; output voltage range -0.3 V to VCC+0.3 V. |
| 3 | VCC | power_in | Chip supply input. Operating range 0.9 V to 6.0 V (absolute max 6 V). Static current ICC ≈ 2 uA typ. (4 uA max) at VCC = 5.5 V, no load. VCC is monitored against Vth = 2.63 V typ. to generate the RESET output. Built-in transient noise rejection on VCC. |
