LM5148-Q1: How to connect the LM5148 overcurrent detection without using ISNS+ and VOUT pins.

Part Number: LM5148-Q1

Due to design reasons, I do not want to use the overcurrent detection function. How should the ISNS+ and VOUT pins be connected?

Hello,

You can please take a try to make short about ISNS+ and VOUT pins.

So what is the recommendation for the ISNS and VOUT pins to be shorted only without grounding or both pins to ground at the same time?

Aim to corrupt the differential current-sense voltages, you can please take a look about 7.3.12.2 Inductor DCR Current Sensing

Section 7.3.12.2 does not explain how to connect when not using current detection. I would like to ask whether the ISNS+ and VOUT pins, which do not require current detection, should be connected by shorting them without grounding or whether they should be grounded together.

May not have grounding
