TPS7H2201-SP: Device behavior beyond maximum voltage input

Part Number: TPS7H2201-SP
Other Parts Discussed in Thread: TPS7H2201-SEP, TPS7H2211-SP, TPS7H2140-SEP

Hi,

I'd like to know how is the TPS7H2201-SEP/SP behavior in case the input voltage reach 10V permanently. Will the output short-circuit with the input level?

Regards and thanks in advance for your support.

    Hi Raúl,

    Unfortunately, since a 10V input voltage is significantly above the limits outlined in the Absolute Maximum Ratings of the device, TI cannot guarantee behavior or performance outside of our recommended operating conditions. Stresses beyond those listed under Absolute Maximum Ratings for any period of time may cause permanent damage to the device.

    If 10V is expected to be applied to the input of this eFuse, the TPS7H2211-SP may be an alternative as it supports up to 14 V VIN.

    Thanks,

    Andy Fondaw

    Hi Andy,

    Thanks for your reply, I seen the alternative but unfortunately TPS7H2211-SP hasn't current sense and programmable current limit. There are other alternatives with this functions?

    Regards

    Hi Raúl,

    Our newly released TPS7H2140-SEP has an input voltage range of 4.5V to 32V and does have current sense, and a programable current limit. It is a 4-channel eFuse, with each channel supporting loads up to 1.35A. If all four channels are configured in parallel, the TPS7H2140-SEP can provide up to 5.4 A.

    I will link the product page here.

    Hi Andy,

    Thanks for the alternative, but it don't fit in our design because it has not configurable OVP.

    Coming back over the out of range behavior for the TPS7H2201. Taking into account that the device can be permanently damaged, I'd like to know if in this case the device short circuit the output with the input.

    Regards

    Hello Raúl,

    Unfortunately, we do not characterize device behavior, including failure modes, outside of the maximum operating conditions. Since we don't do comprehensive testing, there is always a possibility of that type of failure.

    Thanks,

    Andy

    Hello Andy,

    Thanks for your reply and support, now is clear that there are not information about the behavior out of maximum levels neither an expected behavior by design.

    Hello Raúl,

    Are there any further questions I can answer, or support needed on this topic at this time?

    Thank You,
