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 | C1_IN | input | Capacitance channel 1 analog input. Connects to one plate of the C1 sense capacitor; the driven excitation is applied on C1_OUT and the returned charge is integrated here. |+| 2 | C1_OUT | output | Capacitance channel 1 analog output/drive. Applies the excitation waveform to the C1 sense capacitor; forms a differential pair with C1_IN. |+| 3 | C2_IN | input | Capacitance channel 2 analog input. Connects to one plate of the C2 sense capacitor; paired with C2_OUT. |+| 4 | C2_OUT | output | Capacitance channel 2 analog output/drive. Applies the excitation waveform to the C2 sense capacitor; forms a differential pair with C2_IN. |+| 5 | DQ | bidirectional | 1-Wire single-bus data line. Open-drain I/O; requires a ~10 kΩ pull-up to VDD. Carries reset/presence, ROM commands, and function commands per the on-chip 1-Wire protocol. |+| 6 | ALERT | output | Alarm/alert indication output. Asserts when a capacitance measurement crosses a programmed threshold. Drive strength IOH ≈ 1 mA at VDD = 5 V. |+| 7 | VDD | power_in | Supply voltage input. Operating range 2.0 V to 5.5 V (typ 3.3 V); average supply current ≈5.3 µA per capacitance channel measurement. Absolute maximum −0.3 V to +6 V. |+| 8 | VSS | power_in | Ground / power return. The exposed thermal pad (if present) must not be connected to any non-zero potential. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Mysentech |+| Package | SOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `MDC02`+- `MDC02MDC04`++## CAD (KiCad official)++- Symbol: `MDC02`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Mysentech datasheet](docs/mdc02-datasheet.pdf) (39 pp, sha256 `6f34944395558983`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
