5.21.3.1 Device State Control Through PWRON Signal

Figure 5-2 shows the device state control through PWRON signal.

TPS65911 SWCS049-005.gif
  1. The DEV_ON or AUTODEV_ON control bits can be used instead of the PWRHOLD signal to maintain supplies on after a switch-on sequence.
  2. The internal POWER ON enable condition pulse, tdOINT1, keeps device active until a PWRHOLD acknowledge.
  3. Switch-off from PWRHOLD removal.
