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-sense terminal (positive side). Pins 1 and 2 are fused internally and form one end of the low-resistance (0.8 mΩ typ.) copper conduction path used for current sensing. Current flows from pins 1,2 to pins 3,4 for a positive output slope. |+| 2 | IP+ | passive | Primary current-sense terminal (positive side). Pins 1 and 2 are fused internally and form one end of the low-resistance (0.8 mΩ typ.) copper conduction path used for current sensing. |+| 3 | IP- | passive | Primary current-sense terminal (negative side). Pins 3 and 4 are fused internally and form the return end of the internal copper conduction path. |+| 4 | IP- | passive | Primary current-sense terminal (negative side). Pins 3 and 4 are fused internally and form the return end of the internal copper conduction path. |+| 5 | GND | power_in | Signal-side ground reference for the Hall sensor front-end, output amplifier, and control logic. |+| 6 | FILTER | passive | External bandwidth-setting pin. Connect a filter capacitor CF from this pin to GND; it forms an RC low-pass with the internal 1.7 kΩ filter resistance (RF(int)) to trade bandwidth against noise. Typical application uses 10 nF for the specified 120 kHz -3 dB bandwidth. |+| 7 | VIOUT | output | Analog output voltage proportional to sensed primary current. Bidirectional (B) variant is ratio-metric with VCC and centered at VCC/2 at IP = 0 A; sensitivity is 200 mV/A (5 V supply). Drive with RL ≥ 4.7 kΩ and CL ≤ 10 nF. |+| 8 | VCC | power_in | Device supply pin. 5 V ±0.5 V for the AB5 variant; ICC = 10 mA typ. Bypass with 0.1 µF to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSEMITECH |+| Package | SOIC-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `CH70110AB5PR`+- `CH70110BB5PR`+- `CH70110CB3PR`+- `CH70120AB5PR`+- `CH70130AB5PR`+- `CH70140AB5PR`+- `CH70150AB5PR`+- `CH70120AB3PR`+- `CH70130AB3PR`+- `CH70140AB3PR`+- `CH70150AB3PR`+- `CH70120BB5PR`+- `CH70130BB5PR`+- `CH70140BB5PR`+- `CH70150BB5PR`+- `CH70120CB3PR`+- `CH70130CB3PR`+- `CH70140CB3PR`+- `CH70150CB3PR`++## CAD (KiCad official)++- Symbol: `CH70110AB5PR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [COSEMITECH datasheet](docs/ch70110ab5pr-datasheet.pdf) (62 pp, sha256 `bc54e9c5ff632dd6`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
