HX61CN2402MR 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 | N-channel open-drain detector output (HX61CN variant, needs an external pull-up such as the 100K shown in the application circuit), sinking at least 0.5 mA at VOUT=0.2V with VDD=2V and limited to VSS-0.3V to VIN+0.3V. |
| 2 | VSS | power_in | Chip ground pin. |
| 3 | VIN | power_in | Supply and voltage-sense input, operating range 1.5V to 12V with an absolute maximum of 15V; detection voltage is 2.4V (2.328V to 2.472V) for the 24 option. |
