The wake-up comparator indicates a change in cell current while the fuel gauge is in SLEEP modes. Pack Configuration uses bits [RSNS1, RSNS0] to set the sense resistor selection. Pack Configuration also uses the [IWAKE] bit to select one of two possible voltage threshold ranges for the given sense resistor selection. An internal interrupt is generated when the threshold is breached in either charge or discharge directions. Setting both [RSNS1] and [RSNS0] to 0 disables this feature.
IWAKE | RSNS1 | RSNS0 | Vth(SRP-SRN) |
---|---|---|---|
0 | 0 | 0 | Disabled |
1 | 0 | 0 | Disabled |
0 | 0 | 1 | 1.0 mV or –1.0 mV |
1 | 0 | 1 | 2.2 mV or –2.2 mV |
0 | 1 | 0 | 2.2 mV or –2.2 mV |
1 | 1 | 0 | 4.6 mV or –4.6 mV |
0 | 1 | 1 | 4.6 mV or –4.6 mV |
1 | 1 | 1 | 9.8 mV or –9.8 mV |
