Product Number: LTC3886
Hello guys,
in the datasheet of the LTC3886, the absolute maximum rating for the ISENSE1+ Pin is 15V.
However, in a lot of schematics (e.g. on page 1) when using DCR current sensing. the ISENSE1+ Pin is connected (by the Top-MOSFET) to 48V.
sure there is a current limiting resistor in this line, but is this the intended way of usage?
Do you have any feedback where I have to be careful with when using VIN = 50-60V especially with this DCR sensing?
