| 1 battery temp NTC (optional current source) |
| 2 GP |
| 3 temp (with ext. diode, optional current source) |
| 4 GP |
| 5 GP |
| 6 VBAT_SENSE |
| 7 VCC_SENSE |
| 8 Backup Battery voltage |
| 9 external charger (VCHG) |
| 10 VBUS |
| 11 DC-DC current probe (how does this work?) |
| 12 internal die temp |
| 13 internal die temp |
| 14 USB ID pin voltage |
| 15 test network |
