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 | Ground / negative supply return for the device. |+| 2 | RESET | output | Active-low reset output. Driven low when VCC is below Vth (3.08 V typ.) or when MR is low; released high after the Trp delay (500 ms typ.) once VCC recovers and MR is high. VOL ≤ 0.5 V at ISINK = 3.2 mA; VOH ≥ 0.8·VCC at ISOURCE = 500 µA. |+| 3 | MR | input | Manual reset / enable control input, active-low. Driving MR low forces RESET low; a low-to-high transition on MR (with VCC ≥ Vth) starts the Trp reset delay. Logic thresholds: VIH ≥ 0.7·VCC, VIL ≤ 0.2·VCC; minimum pulse width tMR = 10 µs. |+| 4 | VCC | power_in | Positive supply input, 1.0 V to 6.0 V operating range (absolute max 6.5 V). This is also the monitored voltage; RESET asserts when VCC falls below Vth = 3.08 V (typ., ±2.5%). Quiescent current ~2 µA typ. (ICCH max 5 µA at VMR=VCC). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TDSEMIC |+| Package | SOT-143 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `IMP811S-TD`++## CAD (KiCad official)++- Symbol: `IMP811S-TD`+- Footprint: `Package_TO_SOT_SMD:SOT-143`+- 3D model: SOT-143 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TDSEMIC datasheet](docs/imp811s-td-datasheet.pdf) (3 pp, sha256 `f47d2383d09cfbcd`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
