TMUX1072: Is the system protected itself automatic in the event of over-temperature (OTD)?

Tatsuya Yamamoto

Part Number: TMUX1072

Tool/software:

Is the system protected itself automatic in the event of over-temperature (OTD)?

OR, only it output FLT flag?

Please let me know also over-voltage (OVP).

Regards

    Hi,

    The TMUX1072 is not self protected in a OTD event, it however has the ability to alert the system there is a fault using a fault flag

    However the TMUX1072 has both OVP (overvoltage protection) and OVD (Overvoltage detection)

    Please let me know if you need any further assistance 

    Regards,

    Hello Kameron,

    Thank you very much for your answer. I understood clearly.

    Please let me teach how to manage this device after FLT(OTD) flag output.

    Do you have any evaluation report or test repot?

    I want to know how speed CPU should control this device when CPU got the FLT flag.

    I know It will be depend on voltage and current amount. but, I need some sample data.

    Regards

    Hi Tatsuya,

    You will need to add a pull up resistor to the FLT Flag Output to properly use this function in the device.

    The FLT indicator output pin is an open drain output that will require an external pull-up resistor for the overvoltage and overtemperature condition to be detected. If feature is unused, FLT pin may be left floating or connected to ground.

    The Fault output will be pulled low when a fault event occurs with this device.

    In addition our team doesn't have any evaluation reports for this device after a Overtemperature event as this falls outside the recommended operating conditions for this device and performance cant be guaranteed by TI.

    In a overvoltage event this device will actually protect any signal from the com pin from passing to the NC/NO pins and so the cpu in theory wont need to be concerned with the fault flag.

    In a overtemperature event will your cpu beat next to this device and experience the same temperature concerns?( Please correct me If I am wrong)

    Is there any other concern I can try to help with for this device? Please let me know and I am happy to help.

    Regards,

    Kameron
