XC6802A42XPR-G from Torex Semicon, in a SOT-89-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ISEN | input | Charge current setup pin: a resistor RSEN from this pin to VSS sets IBAT = 1000 × VISEN / RSEN with VISEN = 1.0V TYP, IBAT must not exceed 800mA for this package, and an H level (1.4V ≤ VSEN ≤ VIN) or open circuit puts the IC in shutdown. |
| 2 | VSS | power_in | Ground reference pin; all voltage ratings are referenced to VSS. |
| 3 | VIN | power_in | Input voltage pin with an operating range of 4.25V to 6.0V and an absolute maximum rating of -0.3V to +6.5V. |
| 4 | BAT | output | Charge current output to the single-cell Li-ion/Li-Po battery; BAT pin current is rated to 900mA absolute maximum for SOT-89-5, and use must stay within IBAT ≤ Pd/(VIN−VBAT). |
| 5 | /CHG | output | Charge status output with a strong pull-down (10mA TYP) during charge, a weak pull-down (20µA TYP) in stand-by, high impedance in shutdown, and an absolute maximum voltage of -0.3V to +6.5V. |
