**HX hengjiaxing** · Supervisor And Reset ICs · SOT-23-3L

HX61CC2202MR from HX hengjiaxing, in a SOT-23-3L. 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 | VOUT | output | Chip output terminal; CMOS output type for this MPN (ordering code C), with Vout limited to VSS-0.3 V to VIN+0.3 V. |
| 2 | VSS | power_in | Chip ground terminal; the reference for the VOUT limit of VSS-0.3 V and the device ground. |
| 3 | VIN | power_in | Startup/input terminal that supplies the device (VDD = VIN) over the stated operating range of 1.5 V to 12 V, with an absolute maximum input voltage of 15 V. |
