4 / 23 page LC709203F www.onsemi.com 4 Table 1. Pin Function WDFN8 WLP9 Pin Name I/O Description 1 1B TEST I Connect this pin to VSS. 2 1A VSS - Connect this pin to the battery’s negative ( ) pin. 3 3A VDD - Connect this pin to the battery’s positive (+) pin. 4 2A 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 VSS when not in use. 5 3B 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 3C TSENSE I Thermistor sense input. If you connect this pin to thermistor, insert 100 resistance between them for ESD. (Note 1) 7 1C SDA I/O I 2C Data pin (open drain). Pull-up must be done externally. 8 2C SCL I/O I 2C Clock pin (open drain). Pull-up must be done externally. - 2B NC - Connect this pin to VSS. Note 1: TSW and TSENSE must be disconnected as figure 1 when not in use. |
