TLV333 short circuit current (Isc)

Other Parts Discussed in Thread: TLV333

Hi team,


Could you help to explain the short circuit current means?

My customer want to know the short circuit current at -20 & 120 degC. Do you have the data?

Thanks

  • Hi team,

    Please kindly help.

    Pls provide Isc vs Temp chart. or Isc @ -20 & 120 degC

    Thanks
  • Daniel,

    We are working on compiling data and creating short-circuit current (ISC) curves for the TLV333. The data was originally collected at -40 C, 25 C and 125 C so that is what we are able to provide. the graphs should be ready sometime tomorrow.

  • The positive ISC values at -20 C and + 120 C should be close to the those at -40 C and +125 C, respectively.

    Viewing the lower portion of the Figure 5 graph it can be seen that the curves remain mostly flat out to 10 mA, and it is not possible to get an idea of the ISC values when the output is sinking the short-circuit current. Yesterday, some measurment data was found that shows the curves extended out to 50 mA. A new graph was created and it is seen here:

    It can be seen that the TLV333 output current in sinking mode is much higher than in sourcing mode. The actual ISC points still weren't reached, but it does appear that by extrapolating they are approaching around 40 mA at 125 C, 50 mA at 25 C and 55 to 60 mA at -40 C.  Again, I would expect the -20 C and +120 C ISC values to be close to the -40 C and +125 C values, respectively.

  • Dear Tomas,

    Thanks for your great support and explanation.
