|
0 battery type |
|
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 |
