SD5333A from SHOUDING, in a SOT-23-5. 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 | VT | passive | Test pin; only for vendor use and not used by the application. |
| 2 | GND | power_in | Ground; connect the negative terminal of the battery to this pin. |
| 3 | VDD | power_in | Power supply input; absolute maximum -0.3 to 6 V. |
| 4 | VM | bidirectional | Negative terminal of the battery pack; the internal FET switch connects this terminal to GND, absolute maximum -6 to 10 V. |
| 5 | VM | bidirectional | Negative terminal of the battery pack (shared with pin 4); the internal FET switch connects this terminal to GND, absolute maximum -6 to 10 V. |
