PRODUCTION DATA
| NUMBER | NAME | I/O | DESCRIPTION |
|---|---|---|---|
| 1 | VDD | P(1) | Supply voltage |
| 2 | AVDD | O | Analog supply (only connect to a capacitor) |
| 3 | VC5 | I | Cell voltage sense inputs |
| 4 | VC4 | I | |
| 5 | VC3 | I | |
| 6 | VC2 | I | |
| 7 | VC1 | I | |
| 8 | VC0 | I | |
| 9 | VSS | P | Analog ground |
| 10 | SRP | I | Current sense input connecting to the battery side of the sense resistor |
| 11 | SRN | I | Current sense input connecting to the pack side of the sense resistor |
| 12 | DSG | O | DSG FET driver output |
| 13 | CHG | O | CHG FET driver output |
| 14 | LD | I | PACK– load removal detection |
| 15 | LPWR | O | HIBERNATE mode communication pin. Connect to the PRES pin of the lower device in a stack configuration. For a single device, leave the LPWR pin floating. |
| 16 | CBI | I | Cell balancing input. Leave the CBI pin floating to disable cell balancing, and do not drive with an external supply. Drive the pin low to enable cell balancing. In a stacked configuration, connect the CBI pin of an upper device to the CBO pin of the immediate lower device. |
| 17 | OCDP | I | Connecting a resistor from this pin to VSS programs the OCD1/2 fault detection delay. Connect to a 10-MΩ resistor to VSS for the upper devices in a stack. |
| 18 | TS | I | Thermistor measurement input. Connect a 10-kΩ resistor to the VSS pin if the function is not used. |
| 19 | VTB | O | Thermistor bias output |
| 20 | CCFG | I | Cell in-series configuration input |
| 21 | CBO | O | Cell balancing output. Connect through a 10-k resistor to the CBI pin of the upper device in a stacked configuration. For a single device, leave the CBO pin floating. |
| 22 | PRES | I | HIBERNATE mode input. Drive high for NORMAL mode operation. Leave the PRES pin floating for HIBERNATE mode. Connect to the LPWR pin of the upper device in a stack configuration. |
| 23 | CTRC | I | CHG and DSG override inputs |
| 24 | CTRD | I |
