TPS23841 - Software Package

TPS2384: Missing software package

Fabrice Hoffmann

Part Number: TPS2384
Other Parts Discussed in Thread: TPS23861, TPS23881

Hi Support,

I am desperately trying to find the MSP430 software package referenced in the data sheet of the TPS2384.

Regards

    Hi Fabrice, unfortunately for this much older device, we don't have the software available. Very sorry for the inconvenience. We recommend you design with the TPS23861 our newer 4 port PSE in which we have our MSP430 reference code available in its product page. Please see below link.

    Sorry,

    but so you have to correct your datasheet. Even if the device is old, there are reasons to use this device. The software package must have existed each time. Why is that nowhere else to be downloaded ?

    Regards

    Hi Fabrice, yes you're right we will need to update the datasheet and thanks for that feedback! Since this device is around 17 years old, customers designing with this part usually have their own custom software from previously used/existing projects or will operate this device in autonomous mode. Newer projects will typically use our latest device like TPS23861 or TPS23881/882B1 that are compliant to the latest PoE standards. 

    I still highly recommend using the 861/881/882B1 devices since these have been used in many projects and proven PoE compliant designs.

    Hi Darwin,

    tI took a closer look at the documents that you made available to me. Unfortunately, I don't really get along with it. The description of the firmware gives me a certain idea of how the process should be. But since the firmware you made availabe to me is only available as a binary and our MSP has to operate more than just the POE controller, the firmware binaries unfortunately do not help me. I would need the source code.
    In another thread in the "MSP low-power microcontrollers" forum I saw a user asking how to switch the project from IAR to CSS. (https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/360340/converting-tps2384-poe-firmware-version-2-4-iar-to-ccs)

    So the soucre code has to exist somewhere. Isn't it ?

    Hey Fabrice, 

    Is there a reason why you would  not use the TPS23861 in autonomous mode without software? It is lower cost, newer, higher performing, and you do not need to code. We strongly recommend one of the new parts mentioned in the above post. 

    However, if you need code to reference, i recommend looking at the TPS23861 MSP430 reference code on the product page: https://www.ti.com/product/TPS23861#software-development 

    You can alter this code to work with the TPS2384, but please note there is limited support for the TPS2384. 

    If this post answers your question, please indicate so by marking this thread as resolved. Thank you.

    Hey Support Team,

    I don't know the exact reason this TPS2384 is used. But the hardware design is finished and prototypes are available. As far as I know, the TPS2384 is marked as "active" so that there was no reason for our hardware department not to use the chip. Since we cannot use the autonomous mode due to limited power, I just have to do everything by hand. Therefore the source code would simplify my life ENORMOUSLY.
    I just can't understand / accept how such a source code can simply disappear if the chip is still being sold. That just can't be.

    Regards

    Fabrice

    Autonomous mode can be used in limited power applications, I am unsure how it is not useable here?

    Additionally, is there any reason you cannot use the code given above?
