TD1205p battery

Hello,
I plugged a 3V battery on the 1.2 pin but the TD is not powered.

I saw on the TD a 2 pin should make a welding?

Hello,
It is Chevron which is dedicated to un-passivation battery process. If you not used this process, you must to weld this chevron.

Hi
I bought 15 td1205p and all have the same problem. It's not possible to power the device in this way.

Regards

Josep

So yes you must connect these 2 bits in order to power a 1205P with a Battery.

Yes. It works connecting the 2 bits.
Thanks for your help.

And it's possible to connect a fully charge LiPO battery? In every datasheet, the Vmax is 3,6V, but a fully charge battery drops 4,2v. It's possible to damage the TD1205p ?

Hello!, I have the same question, becouse I saw in a project the TD1205P supply by a Lipo battery but in the datasheet Vmax is 3.6V. Have you tried to test this?

Have Somebody tried to supply the TD1205P by a Lipo battery?

The provided absolute maximum ratings are there because of good reasons, mainly internal components that are not guaranteed to continue working if you go beyond these values.

If you don't respect the absolute maximum ratings from the datasheet, then you are on your own!

You may put a diode in series in order to get a sufficient voltage drop, but I never tried.
