3.11. High VCCBAT Current when VCC is Powered Down

If you power off VCC when VCCBAT remains powered on, VCCBAT may draw higher current than expected.

If you use the battery to maintain volatile security keys when the system is not powered up, VCCBAT current could be up to 120 µA, resulting in shortened battery life.

Workaround

Contact your battery provider to evaluate the impact to the retention period of the battery used on your board.

There is no impact if you connect the VCCBAT to the on-board power rail.
