Part Number: LSF0204
Other Parts Discussed in Thread: TIDA-01014

Tool/software:

Hello，

As shown in the figure below, the recommended maximum value for Ven in the data manual is Vrf-A, but the Ven on reference design TIDA-01014 is directly connected to Vrf-B. Why? Please help to answer.

Thanks！

    The EN pin is overvoltage tolerant; any voltage between Vref_A and 5.5 V is read as high.

    Also, the allowed range for Vpu is from Vref_A to 5.5 V.

    Hi Jeno,

    Generally speaking, reference diagrams should not be copied directly due to small inaccuracies such as this (they should be used only as a top-level reference). Customers should always consult with device data sheet for proper setup. 

    Clemens' is correct here with the suggestions, and if a further schematic check per your specific application is needed, please share here. 

    Regards,

    Jack
