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 | IP+ | passive | Primary current input positive terminal. Internally tied to pin 2; short pins 1 and 2 together on the board. Part of the low-resistance (1.5 mΩ typ.) isolated primary conductor path with pins 3/4. |+| 2 | IP+ | passive | Primary current input positive terminal. Internally tied to pin 1; short pins 1 and 2 together on the board. Part of the isolated primary conductor path (1.5 mΩ typ.). |+| 3 | IP- | passive | Primary current input negative terminal. Internally tied to pin 4; short pins 3 and 4 together on the board. Return side of the isolated primary conductor path. |+| 4 | IP- | passive | Primary current input negative terminal. Internally tied to pin 3; short pins 3 and 4 together on the board. Return side of the isolated primary conductor path. |+| 5 | GND | power_in | Signal ground reference for the low-voltage side of the sensor. Electrically isolated from the primary current conductor pins (2.6 kVrms dielectric isolation, SOP-8). |+| 6 | FILTER | passive | Bandwidth-setting filter pin. Connect an external capacitor (CFILTER) to GND to reduce bandwidth and optimize output noise. Internal filter resistance is 1.8 kΩ typical; default internal bandwidth is 150 kHz. |+| 7 | VOUT | output | Analog output voltage proportional to the primary sensed current. Ratiometric from VCC with quiescent (0 A) output = VCC × 0.5 (2.5 V typ. at 5 V), sensitivity 200 mV/A, output range 0.5 V to VCC-0.3 V, DC output resistance 5 Ω typ. Drive up to 80 mA source / 40 mA sink. |+| 8 | VCC | power_in | Positive supply input, 4.5 V to 5.5 V (5.0 V nominal). ICC = 14 mA typ. (20 mA max). Requires a 0.1 µF bypass capacitor to GND close to the pin. Power-on reset thresholds: VPORH = 4 V typ., VPORL = 3.5 V typ. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Magn Tek |+| Package | SOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `MT9221CT-10BR5`+- `MT9221CT-10BR5QT`++## CAD (KiCad official)++- Symbol: `MT9221CT-10BR5`+- 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:** [Magn Tek datasheet](docs/mt9221ct-10br5-datasheet.pdf) (None pp, sha256 `6687bbd3c43ad19a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
