XB8089D from XySemi, in a SOIC-8-EP. 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 | VM | input | Negative terminal of the battery pack sense/switch node. The internal FET switch connects this terminal to GND during normal operation. Used to sense charger/load presence and overcurrent (rated -6 V to 10 V absolute max). |
| 2 | VM | input | Negative terminal of the battery pack sense/switch node (paralleled with pins 1/3/4). |
| 3 | VM | input | Negative terminal of the battery pack sense/switch node (paralleled with pins 1/2/4). |
| 4 | VM | input | Negative terminal of the battery pack sense/switch node (paralleled with pins 1/2/3). |
| 5 | GND | power_in | Ground. Connect the negative terminal of the battery cell (BAT-) to this pin. |
| 6 | VDD | power_in | Power supply input. Connect to BAT+ through the recommended 1 kΩ series resistor (with a 0.1 µF decoupling cap to GND). Absolute maximum VDD is -0.3 V to 6 V. |
| 7 | GND | power_in | Ground. Tied to pins 5 and 8; connect to the battery negative terminal. |
| 8 | GND | power_in | Ground. Tied to pins 5 and 7; connect to the battery negative terminal. |
| 9 | EPAD | power_in | Exposed thermal pad on the underside of the SOP8-EPAD package. Must be soldered to the GND copper pour of the XB8089D for proper thermal dissipation and current handling. |
