Hi
I am trying to use LMP92064 in our design to sense load current. but it was mentioned as low side sense. our design has a high side current sense resistors. can I use LMP92064 for high side current sense application?
thanks

Hello Karthic,
Thanks for reaching out on the forum. As Kai noted, the parts recommended operating range for the common mode input voltage range only extends to 2V. So unless your high-side voltage stays within this bound, this would not be a good fit for your design. That being said, what specifications do you need for your current sensing solution? For example, what will be your common mode voltage, supply voltage, desired max output voltage, current range, and max desired error? If you are unfamiliar with current sensing devices, I would recommend watching our tutorial video series (training.ti.com/getting-started-current-sense-amplifiers). Also one thing to note is a lot of our specifications actually are provided to help determine the error you will see for any given operating conditions. If you click on any of the products listed in the parametric search (http://www.ti.com/amplifier-circuit/current-sense/power-current-monitors/products.html ) and go to its respective product folder, in most cases on the right side of the browser window, you will see an error curve calculator that can help assist you in assessing how the part may perform in your system.
