DAC8775: Min current limit for short detect.

Motoyasu Hattori

Part Number: DAC8775

Hi,

My customer considers the short_detect on each voltage output lines.
According to the datasheet P.40, we can find the following.

>>A short circuit current limit is reached (> 500 µsec) on any VOUT_x when enabled in voltage output mode.

He observed the error bit is occurred when much current is flow on voltage mode. Could you please let us know how much MIN current limit for short circuit?   In other words, could you please let us know current limit of Fault condition to indicate FA/FB/FC/FD bit on voltage mode for short circuit?

Thanks and best regards,
M.HATTORI.

    Hi Hattori-san,

    The minimum short circuit current that can trigger the alarm state is set by the SCLIM field in the device register.  We specify the minimum current for each of the SCLIM settings in the parametric table:

    Thanks,
