Hibernate mode puts the application in very low consumption mode. During this phase, the con-
sumption is less than 2mA. In order to achieve this, all the main LDOs are switched off (LDO1,
LDO2 and LDO3) by activating the “twck” pin to low level. Only LDO4 remains active so that the
baseband RTC block may continue working.
To wake up the device (equivalent to quitting Hibernate Mode), a high level should be applied on
the “twck” pin. This switches on the main LDOs.
