Power Muxing for primary battery and USB-Power with deep discharge protection

Hello Jens,

Indeed the E2E forum is the correct place to go for technical questions about TI devices and applications.
The forum is monitored by members of the individual product groups, very specific to the devices they own.

Therefore general questions, such as yours, that cross many product boundaries need to be split so the correct groups can reply.

Below are URLs for separate threads that I created for each team – if you click on “Options” (assuming you are logged in), you can subscribe to reply notifications for each of these threads – you will receive replies for each of these within one business day.
You can also reply to these threads for further discussion.

- usb2 connection for 5V and data -> EMI components needed

https://e2e.ti.com/support/power-management/f/196/t/883392

- primary battery with 3x AA as alkaline or NiMh
- deep discharge protection for the battery needed, disconnecting from load, automatic reset if new batteries are inserted

- switch for selecting voltage source, batteries should not be charged, perhaps TPS2115A

- LDO for 3.3V (200-500 mA peak) needed

For future questions please try to keep it specific to a particular device family.
When creating a new thread question, try to use a Part Number close to or similar to the part you would be interested in.
       The part number will assure the fastest routing to the product team for the fastest answer.
