Part Number: TPS23753
i want to check which condition, the TPS23753 cannot replace TPS23753A.
I have seen the ESD from the first page. But don't know how to understand it.
Could you please help describe it more detail？ And how to convince the customer to use the tps23753 to replace TPS23753A?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Frank Xiao:
Frank, We recommend the 'A' version in all cases as the TPS23753A has improved soft failure immunity. Otherwise, there are no functional or parametric differences between the two options. The TPS23753A was released in order to avoid an issue where the TPS23753 (non-A) could glitch off (soft failure) during a system-level ESD event.
The additional ESD immunity is circuitry internal to the IC...nothing pins out. We keep the non-A version active for customers who designed that solution in first, are happy with it's performance, and have no need to qualify the 'A.'
Otherwise, we always recommend the 'A' version to new customers. Thank you for your local support of PoE products,
