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 | /CHG | output | Charge status output pin. Open-drain (weak/strong pull-down + high-Z states) intended to drive an external status LED. Strong pull-down current 10mA (typ) at VBAT=4.0V, weak pull-down 20µA (typ) at VBAT=4.3V. Absolute-max pin voltage -0.3 to +6.5V. |+| 2 | VSS | power_in | Device ground reference. All pin voltages are referenced to VSS. |+| 3 | BAT | power_out | Charge current output pin - connects to the positive terminal of the Li-ion / Li-Po cell. Regulated to the 4.2V ±0.7% float voltage in CV mode; supplies up to 800mA (SOT-25). Absolute-max pin voltage -0.3 to +6.5V, IBAT(max) 900mA. |+| 4 | VIN | power_in | Input supply pin. Operating range 4.25V to 6.0V; absolute-max -0.3 to +6.5V. UVLO releases at ~3.8V (typ). Decouple with 1µF ceramic to VSS as shown in the typical application. |+| 5 | ISEN | input | Charge current setup / shutdown pin. A resistor RSEN to VSS programs IBAT = (VISEN/RSEN) × 1000 with VISEN ≈ 1.0V (typ). Driving ISEN High (1.4V ≤ VSEN ≤ VIN) or leaving it Open forces Shutdown Mode. Absolute-max -0.3V to VIN+0.3V (or +6.5V, whichever is lower). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Torex Semicon |+| Package | SOT-25 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `XC6802A42XMR-GMR`+- `XC6802A42XMR-GMR-G`+- `XC6802A42XMR-GPR`+- `XC6802A42XMR-GPR-G`+- `XC6802A42XMR-GER`+- `XC6802A42XMR-GER-G`+- `XC6802A42XMR-G4R-G`++## CAD (KiCad official)++- Symbol: `XC6802A42XMR-G`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-25 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Torex Semicon datasheet](docs/xc6802a42xmr-g-datasheet.pdf) (21 pp, sha256 `8c74af77a162dbe8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
