Pin Configuration
| Pin | Name | Type | Description |
|---|---|---|---|
| 1 | TEST | I | Connect this pin to V SS . |
| 2 | V SS | - | Connect this pin to the battery's negative ( ) pin. |
| 3 | V DD | - | Connect this pin to the battery's positive (+) pin. |
| 4 | ALARMB | O | This pin indicates alarm by low output(open drain). Pull-up must be done externally. Alarm conditions are specified by registers (0x13 or 0x14). Connect this pin to V SS when not in use. |
| 5 | TSW | O | Power supply output for thermistor. This pin goes HIGH during temperature read operation. Resistance value of TSW (for thermistor pull-up) must be the same value as the thermistor. (Note 1) |
| 6 | TSENSE | I | Thermistor sense input. If you connect this pin to thermistor, insert 100 resistance between them for ESD. (Note 1) |
| 7 | SDA | I/O | I 2 C Data pin (open drain). Pull-up must be done externally. |
| 8 | SCL | I/O | I 2 C Clock pin (open drain). Pull-up must be done externally. |
