TPS24750: How to set current limit current?

Hi team,

I have some questions about current limit point.

1. Datasheet shows current limit threshold in page 7 is 22.5mV~27.5mV, typical is 25mV. But in page 26, why the threshold is allowed from 10mV~42mV?

2. Is the current flow through Rset equals to current flow through IMON pin?

Thank you.

    Hi,

    1A) The device characertization is done at 25mV threshold but you are free to select b/n 10mV~42mV based on system noise and power loss considerations in your design

    2A) correct. Rset current equals to current flow through IMON pin

    Best Regards,
