Hi!
I'm designing a power supply using TPS2121 to switch between USB and internal AAA battery. Battery is used when USB (VBUS in the attached schematic) is not available.
However, the device also has a power switch, which should switch the device completely off without draining any of the power supplies. The switch is a one-pole switch, but needs to disable BOTH power supplies. Is there any way to connect this to the TPS2121 to achieve a complete shutdown? Looking at Table 9-3 in the datasheet, the only case where the output is completely off seems to be when both input supplies are invalid, but maybe I'm missing something.
BR, Jon
