TPS2051B: reliability with external 5VDC applied to the output

Lenio Cacula
Genius 15900 points
Part Number: TPS2051B

Can the TPS2051B be potentially damaged when 5VDC is applied to its outputs and the device is not powered? I am curious for the transitions not only on the output, but also on the power of the TPS2051B itself. Could there be any specific case that could create a damaging operating condition for the device?

I understand that the TPS2051B may or may not prevent reverse current in case the outputs have 5VDC applied to them (it will depend on the enable pin). That is not a concern for this application however.

Thank you!

    Hi,

    The ABS of TPS2051B is 6V. It will  not break the part with 5V at output.

    1. Don't  be out of the range of spec.

    2. Input and output cap should be added as required by datasheet.

    For TI's policy, I will first click resolved button.

    If you have any other concern, contact me any time.

    If you think resolved, please help click 'Issue is solved button'.

    Thanks.
