8.3.4 BACKUP State

In the BACKUP state only the battery is supplying power to the device, however the device must have gone through a VDD supplied state (and loaded configuration data) in order to enter this state. If no VDD supplied state has occurred, then the TPS38700S-Q1 stays in the "OFF or Battery Installed" state, from which it will exit only with a valid VDD supply. I2C commincation with TPS38700S-Q1 is possible when in this state.

When in BACKUP state, the TPS38700S-Q1 pins are in the following state:

  • ENx = Low (de-asserted)
  • NRST = Low (asserted)
  • ACT input is ignored.
Upon exiting from the BACKUP state, the last configuration is active and the device enters the SHDN state.
