8.3.3.2 Wake-Up Comparator

The wake-up comparator is used to indicate a change in cell current while the bq27546-G1 is in SLEEP mode. 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.

Table 1. I_WAKE Threshold Settings⁽¹⁾

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

(1) The actual resistance value vs. the sense resistor setting is not important; however, the actual voltage threshold when calculating the configuration is important. The voltage thresholds are typical values under room temperature.
