Part Number: XTR106
Hi Team,Our customer needs to work with XTR106 for their application and they are concerned if ever their end-user will use it above the recommended operations of the device, causing a '36mA' output if that possible, or, they supplied it with over 36VDC.- The datasheet concern is the Over-Scale Limit; typical 28mA, max 30mA. What happens if the bridge input is telling it to go to 36mA? Will it damage or just saturated? As their end-user wants it in this state for 30 minutes.Their PCB is already made for XTR106 so redesigning is not possible.If the XTR106 will get damage, is it immediate or will it take some days or years?Thanks,Jonathan
Thank you for your post, I can help you.
Unfortunately, we don't have performance details beyond the datasheet limits. We recommend that our customers use the device under the specified conditions of the datasheet. We are not able to comment on the performance of the device beyond the limits in the datasheet, as these can lead to unpredictable behavior and damage. We also don't recommend that you operate at these maximum ratings as that can also lead to unpredictable behavior and damage.
See page 3 of the datasheet for these absolute ratings:

We are glad that we were able to resolve this issue, and will now proceed to close this thread.

the XTR106 provides an over-scale current limit. Please have a look into the datasheet of XTR106. The over-scale current limit prevents the output current from rising above the current "the bridge input is telling".
Figure 6 of datasheet shows how to handle too high supply voltages. Choose the threshold voltage of D1 appropriately so that the supply voltage of XTR106 can never exceed 40V. Add a current fuse or a thermal fuse (which you put close to D1) to protect D1 against excessive currents.
Keep in mind that the XTR106 circuit is the more stressed the lower the burden (shunt, load) is. Because of this, a short circuit at the output of XTR106 (pin 7) will cause the highest heat dissipation. If your circuit cannot stand this condition improve the cooling of XTR106 and especially the external pass transistor.
