Operating range 1.65V to 5.5V; absolute max 6V. Recommend 0.1uF decoupling capacitor to GND at the pin. |+| 2 | OUT | output | Push-pull digital output. Pulled low when |B| > Bop (typ ±33 Gauss) and driven high when |B| < Brp (typ ±23 Gauss). Sink/source capability 1 mA (VOL 0.2V max at 1mA, VOH VDD-0.2V min at -1mA). |+| 3 | GND | power_in | Ground reference pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSEMITECH |+| Package | SOT-23-3L |+| Category | Sensor |+| Pins | 3 |++## Ordering variants++- `CH912LSR`+- `CH912LSRTB`++## CAD (KiCad official)++- Symbol: `CH912LSR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [COSEMITECH datasheet](docs/ch912lsr-datasheet.pdf) (9 pp, sha256 `d1118d62b1014ac0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
