Satoshi
Guru 19645 points
Part Number: TPS2549

Please let me know about mean of "Internally limited" on TPS2549 Absolute maximum rating?

If there fixed current and temperature absolute maximum rating, please let me know together.  

Best regards,

Satoshi

    Hello Satoshi,

    You can set the output current limit is variable, and can be set based on the resistance connected to ILIM_HI and ILIM_LO. Section 8.3.10 of the datasheet explains the current limit feature, as well as how to calculate the resistance to connect to each ILIM pin.

    Further, you can refer to Table 2 within the datasheet to know which ILIM pin is referenced based on the mode you have the device in.

    Hope this helps answer your question.

    Thank you for reply,

    I understood about points of current limit.

    Additional question, why operating junction temperature described "internally limited"?

    Best regards,

    Hi Satoshi-san,

    The TPS2549 has over-temperature protection so that the Junction Temperature is internally limited.

    Thank you,
