SD5820A from Hangzhou SDIC Microelectronics, in a TO-92. 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 | Ground connection for the sensor; parasitic-power mode requires VDD to be tied to this ground. |
| 2 | DIO | bidirectional | Open-drain single-wire data port that needs an external pull-up resistor, with a minimum 4 mA sink current at VOL=0.3 V and maximum 1 uA high-level leakage at VOH=VDD. |
| 3 | VDD | power_in | Supply pin with a 2.7 V to 5.5 V operating range (3.0 V typical); the device can also run in parasitic-power mode drawn from the bus. |
