TMCS1123: Hall element material investigation request

Part Number: TMCS1123

Hi,

Regarding device tmcs1123, could you please help clarify the following points?

What is the material used for the Hall element?
When used long-term, which behavior best represents the characteristic change of the Hall element?
- Pattern 1: Gradual change over time
- Pattern 2: Sudden change after certain operation time
If the Hall element characteristics shift, are the main affected parameters “current sensitivity,” “zero-current voltage,” and “linearity”?
For galvanic isolation, is it achieved solely by mold resin, or is there an internal insulating material such as polyimide tape?
Please provide the dielectric thickness (DTI).
If insulation is based on mold resin, do you have test results for withstand voltage degradation under high-humidity conditions?
For insulation lifetime evaluation, I assume accelerated tests with high voltage are performed. How do you determine whether failures are due to wear-out mechanisms?

Thanks,

Conor

Conor,

I spoke with my systems team, and the information being asked here speaks directly to the IP of the device. We cannot disclose these details.

Hi Carolus,

We fully understand that the internal structure of the device is part of TI’s intellectual property and cannot be disclosed.

We are not asking for any IP-related structural details, but only for responses that can be shared based on publicly available information.

Of the seven questions listed above, could you please answer as many as you are able to within that scope?

Thanks,

Conor

Conor,

Let me circle back with the systems team and see if there is anything on this list we can address for you. I will follow up shortly.
