Figure 4. Wake-up input signal behaviour
Condition summary:
1.
No change of sleep mode state but current consumption may exceed specification for
sleep mode.
2.
The sleep mode current returns within the specified limits.
3.
Power supply exits sleep mode. Switchers start operating if applicable voltages exceed
under voltage lockouts. As Twakeup time-out is not elapsed, a low level at WAKEUP
instantaneously sends the system back to sleep.
4.
Sleep Reset is released and the entire system starts operating. A SPI command to
enter sleep state would be ignored.
5.
No change in system status, a SPI command to enter sleep state would be ignored.
6.
No change in system status, but a SPI command to turn off switchers would be
accepted and turn the system off.
With the below table, all the functionalities of the device are shown with respect to the power
states. When one function is flagged, the related circuitry cannot be activated on that state.
