TPS552872-Q1: Input and enable slew rate requirements

Abdulkader Al-Obaidi

Tool/software:

Are there any slew rate requirements on the power supply input or enable inputs? is there a concern that a fast slew rate can falsely trigger the ESD circuitry and cause the IC to miss-behave

Hi Abdulkader,

Thank you for reaching out. For EN pin, 8ns rising time is ok. For Vin, slew rate slower than 1V/20us will be ok.

Thank you, can these values be found in datasheet?

Hi Abdulkader,

The recommendation is based on our bench test experience. There is no specific value in datasheet.
