We are currently evaluating the following STMicroelectronics IC for our application:
SPV1040TTR
As part of our reliability and performance assessment, we kindly request your support in providing:
  1. Temperature vs. efficiency curves across the specified operating temperature range
  2. MTBF (Mean Time Between Failures) data or estimated MTBF hours for the above-mentioned ICs

You have already created a ticket with the internal ticket number 00254037 today, and I would ask you to wait for a response from that team. The community will not really be able to help you with your question, as it is a global forum for mutual assistance between users.

Thank you for your understanding and patience.

    As I can see now, the OLS team has referred you to the community, which is definitely not correct. However, I can already say that an NDA (Non Disclosure Agreement) is necessary to get MTBF data, which definitely has to be handled via the OLS.

    However, regarding your first question, I cannot give you any hope of obtaining efficiency curves, especially over temperature, because this depends on a great many external parameters. Among other things, the number of cells to be charged plays a very important role. The device was launched on the market back in 2010, so the probability of such a data sheet supplement is virtually zero.

    Can you atleast provide with the junction to case thermal resistance (Rthjc) for the IC.

    Thanks.
