TPS272C45: Minimum overcurrent limit threshold & paralleling FLT

Guenter Fettig
Intellectual 1540 points
Part Number: TPS272C45


Datasheet not specifying minimum overcurrent limit threshold at overload condition.

How to ensure, under normal load condition, overload not triggered ?

For instance: Rlim=10k, Iload=2A    --> max. DS value is 2.42A, min. value ?

Is it possible to parallel FLT pins, if paralleling several TPS272C45 ?

    Hi Guenter,

    For normal load (current creep) condition, you can assume the same minimum as overload condition, which means the current limit can trigger as low as 1.58A. You will ensure the system normal current will be below 1.58A in this case to not trigger the current limit.

    For the Fault signal, it's possible to parallel them and they will be OR'd to report the fault.

    Please let me know if you have additional questions.

    Regards,

    Yichi
