XB5606AJ from XySemi, in a SOT-23-5. 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 | GND | power_in | Ground; connect the negative terminal of the battery to this pin. Tied together with pin 2 on the package (both are GND). |
| 2 | GND | power_in | Ground; connect the negative terminal of the battery to this pin. Tied together with pin 1 on the package (both are GND). |
| 3 | VDD | power_in | Power supply input; connects to the battery positive terminal via a 1 kΩ series resistor and 0.1 µF decoupling capacitor to GND. Absolute maximum -0.3 to 6 V. |
| 4 | VM | bidirectional | Negative terminal sense of the battery pack (charger-/load- node). The internal FET switch connects this terminal to GND during normal operation. Sensing this pin's voltage relative to GND performs charger detection and overcurrent / load short-circuit detection. Absolute maximum -6 to 10 V. Tied to pin 5. |
| 5 | VM | bidirectional | Negative terminal sense of the battery pack (charger-/load- node). Second VM pin used to carry the high-current path from the internal FET switch to the pack negative rail. Tied to pin 4. |
