Dear all,

Could you give some advece about TPS24751?

Our customer design the board using TPS24751.

Then,they try to design to connect to the 3 resistances in series as Rsense.(like figure below.)

If this way is not OK, please give some advices.

It would be great if you could let me know your thoughts this cause.

Hi,

Thanks for reaching out.

I do not see any concern in using three resistors in series. But please follow kelvin sensing (refer datasheet layout guidelines) and blog e2e.ti.com/.../choosing-the-right-sense-resistor-layout

May I know the reason for three resistors in series ?

Best Regards,
Rakesh
