TPS3825: TPS3825 max current

Tomas Heitel
Prodigy 90 points
Part Number: TPS3825

Dear TI Team,
what is the max current at the MR input pin of the TPS3825? May I connect  1 pushbutton to 3 TPS3825? From the datasheet I can see that there is an internall pull-up (52kohm) so it should be possible from my point of view.
Thank You for support.

    Hello Tomas,

    The ABS MAX rating for all input pins is +/- 5 mA.

    According to the EC table 7.5, the max low level input current expected for /MR when /MR is logic low is -160 uA. So 3x this current is 480 uA which is well within the ABS MAX. This means that using a push-button on three separate TPS3825 devices is OK and does not violate the max ratings. Please let me know if you have any additional questions otherwise I will consider this item closed. Thanks!
