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 | REF | input | Reference voltage input. Sets the output voltage when VSENSE = 0 V (VOUT = ILOAD × RSHUNT × GAIN + VREF). Typically tied to GND for unidirectional sensing or to VS/2 for bi-directional sensing. |+| 2 | GND | power_in | Ground return for the device. |+| 3 | V+ | power_in | Positive supply input, 2.7 V to 30 V (42 V absolute max). Typical quiescent current 120 µA. A 0.01 µF to 0.1 µF bypass capacitor to GND is recommended. |+| 4 | IN+ | input | Non-inverting current-sense input. Connects to one side of the external shunt resistor. Common-mode range -0.3 V to +36 V, independent of supply voltage. Input current limited to ±10 mA absolute max. |+| 5 | IN- | input | Inverting current-sense input. Connects to the other side of the external shunt resistor. Common-mode range -0.3 V to +36 V, independent of supply voltage. Input current limited to ±10 mA absolute max. |+| 6 | OUT | output | Rail-to-rail analog output. VOUT = (ILOAD × RSHUNT) × 200 + VREF for the A3 variant. Output current absolute max ±35 mA; max capacitive load 1 nF. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | 3PEAK |+| Package | SC-70-6 |+| Category | Amplifiers/Comparators |+| Pins | 6 |++## Ordering variants++Same part, different packaging or reel option.++- `TP181A3-CR`++## CAD (KiCad official)++- Symbol: `TP181A3-CR`+- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`+- 3D model: SC-70-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [3PEAK datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8602879103309520896) (11 pp, sha256 `8d0b48242ab0414d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
