Pins should be connected to the appropriate circuits, as shown in the simplified diagrams in Section 9.2 and as described in the Section 6 section. See Table 9-1 for additional comments.
| PIN NAME | RECOMMENDATION |
|---|---|
| DSG, CHG | DSG and CHG are outputs and may be left unconnected if not used. |
| VSS | Must be used |
| SDA, SCL | Must be used |
| TSn | Must have a thermistor or pull down resistor to the group reference. TS1 must have a rising edge to boot the part. |
| CAPn | A capacitor must be installed. |
| REGOUT | REGOUT also supplies internal circuits. A capacitor must be installed even if REGOUT is not used for external circuitry. |
| REGSRC | Must be supplied |
| BAT | Primary power pin for the part, must be connected to the top cell through the power filter |
| VC5x, VC10x | Must connect to the appropriate cell through the power filter |
| NC | Some pins named NC must be connected to the appropriate CAPn pin. See Section 6. |
| VCn | Cell voltage sense input pins. Must be connected through the input filter to the cells. When not all cells are needed, connect as described in Section 9.1.8. |
| SRP, SRN | Current sense inputs. When not used, connect to VSS. |
| ALERT | When not used, a pulldown is recommended. See Section 9.1.4. |
