BAT is used only for internal protection circuitry. If VBAT goes more positive than -10 V, the device will enter the all-off state and will remain in the all-off state until

the battery goes more negative than -15 V

Power requirements

talk and all-off states

VDD = 5 V, VBAT = -48 V, measure IDD
