BQ24311DSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 | IN | power_in | Input power pin to external DC supply; input voltage range 3-26V. |
| 2 | VSS | power_in | Ground pin. |
| 3 | NC | unconnected | No connection pin; for internal test purposes only. |
| 4 | FAULT | tri_state | Open-drain status output that goes low on input overvoltage, input overcurrent, battery overvoltage, or thermal shutdown. |
| 5 | CE | input | Chip enable input, active low; internal FET turns off when CE = High; internally pulled down. |
| 6 | VBAT | power_in | Battery voltage sense input; connect to battery positive through a resistor. |
| 7 | ILIM | bidirectional | Overcurrent threshold programming pin; connect resistor to VSS to set threshold between 50-300mA. |
| 8 | OUT | power_out | Output power pin to charging system; output current range 50-300mA. |
| 9 | Thermal PAD | passive | Exposed thermal pad internally connected to VSS; must be soldered to PCB ground plane for thermal performance. |
