from VBAT to ground when the VDD_MCU/DC+ level falls below VBAT, but this leakage current should be
small compared to the current from VDD_MCU/DC+.
The amount of time that it takes for a device configured in one-cell mode to wake up from Sleep mode
depends on a number of factors, including the dc-dc converter clock speed, the settings of the SWSEL and
ILIMIT bits, the battery internal resistance, the load current, and the difference between the VBAT voltage
level and the programmed output voltage. The wake up time can be as short as 2 µs, though it is more
commonly in the range of 5 to 10 µs, and it can exceed 50 µs under extreme conditions.
See Section “14. Power Management” on page 151 for more information about sleep mode.
