Part Number:TPS25921A
Hi,
We are using this device in many designs. Works fine as is. TPS25921A
BUT, during worst case circuit analysis, the wide range of the I Lim Current 6us to 16 ua ( page 5 of data sheet) is causing problems for us. WE would not be able to meet our minimum current limit requirement without major changes.
We used 10.73 ua as per your application notes for the current limit set point.
Our question is this.
WE are using this device only from -20 DEg C to +85 DEg C.
What would the tolerance be for the I LIm at this temp range ?? Do you have anything in writing that would show a tighter tolerance for this I LIm current.
Would there be a graph available that shows this ?? perhaps I LIm vs temperature ?
At this time, this wide tolerance is causing a major problem where we cannot ship product without changes.
Thanks,
