Part Number: OPA549-HIREL

Hi,

Can I use the voltage at the ILIM pin of OPA549-HiRel as the current monitor?

  • The apps engineer supporting this device will respond to your inquiry upon his return to the office on Friday.

    Thanks.
  • Hi Benyuan,

    No, the ILIM pin can not be used in this way as the current through this pin is not related to the output current. This pin just sets a reference point to compare against the output current for limiting purposes, the output current sensing is done internally.

    Best,
