Part Number: TMS37145
Other Parts Discussed in Thread: TMS37126

Hello!

I want to install 4.2V battery instead of a 3V battery.
Is the TMS37126 approved for overvoltage?

I know that the datasheet is up to 3.6V.

Hi Sergey,

using 4.2V for the device is not tested and not approved form TI. 3.6V is defined as absolute maximum voltage for this device. You will need to add a regulator when using 4.2V.

Best Regards,

What's the difference between 37126C3X and TMS37126D3X?

And why is there no information on the site on TMS37126?

Hi Sergey,

the datasheet to this device is only available with a valid NDA. They are not supported at the E2E forum.

Please contact your local TI sales for more information.

Best Regards,

Helfried
