LM4128-Q1: Enable pin input level

Part Number: LM4128-Q1

Tool/software:

Hello,experters

         when I use to LM4128-Q1,as below,IO power of enable pin input level is same as VIN voltage or any input level is ok.

In the datasheet ,I can not see to relation to enable threshold level of rising.

thank you 

  • Hi Wenjun,

    Yes the same EN voltage as the VIN voltage is recommended. You can also have a separate rail voltage as long as it does not exceed VIN voltage and is at least 65% of VIN for enabled state and below 35% of VIN for disabled state. The EC table values you highlighted are percentages of VIN voltage.

    Thanks,
