Hello,

Please let me know the min/max value of Reset threshold(UVthres) with VOUT=3.3V, in TPS7A6333-Q1.

(I can see these value with VOUT=5V in TPS7A6350 and I think it has variation about +/-3%.  Why there is only typical value in 3.3V?

And  is it acceptable that it has the same variation in 3.3V too ?)

 

Thanks,

Hiroshi Sato

    Hiroshi-san,

    The UVLO-treshold is set at 93% of the output voltage typical (see detailed description on page 12 of the datasheet).

    Please expect about the same tolerance (+/-3%) of this parameter for other output voltages (3.3V for TPS7A6333 or whichever output voltage is set for TPS7A6301 or TPS7A6401).

    I will check if we can add the tolerance with a new revision of the datasheet.

    Best regards,

    Frank

    Frank-san,

    Thank you for your quick replying. This is useful information.

    And if the tolerance value  could be added in the datasheert, our customer will be more relieved.
