| NUMBER | NAME | TYPE | DESCRIPTION |
|---|---|---|---|
| 1 | BAT | I(1) | BAT voltage sensing input (connected to the battery side) |
| 2 | VDD | P | Supply voltage |
| 3 | VSS | — | Device ground |
| 4 | CS | I | Current sensing input (connect to PACK– side of the sense resistor) |
| 5 | CTR | I | Active high control pin to open FET drivers and shut down the device. It can be configured to enable an internal pull-up and connect the CTR pin to an external PTC for OT protection. |
| 6 | PACK | I | Pack voltage sensing pin (connected to the charger side, typically referred to as PACK+ and PACK–) |
| 7 | DSG | O | DSG FET driver |
| 8 | CHG | O | CHG FET driver |
