Hi Teams,

Since I used Rsense=0.1ohm, will the limitation of the Rhold still 66.67k to 333k?

I changed to Ihold=0.25A, with Rhold=400k, but the current waveform Iout=~0.5A. I am wondering how this happen?

Best Regards,

Hi Gene,

Rsense does not affect the equation, when Rsense=0.1ohm and Rhold=400kohm Ihold should be 0.25A
Seems to me other external components affect Ihold, please e-mail me details at "costin.cazana@ti.com"

Best Regards,
