Original question:
How will this component do if someone shorts the 24v wire with the current return wire, during operation? Will the component be damaged? And lets say that the reference design has been implemented.
Will there be damage to the device if someone were to short a Vref or Vreg line to the Iin or Iret?
thanks
Hi Chad,
How will this component do if someone shorts the 24v wire with the current return wire, during operation? Will the component be damaged?
Per the fault scenario above, the XTR116 is capable to survive the short condition. Assume the Vin = 5V or sourcing 32mA_max at 24Vdc, The external resistor Q1 will dissipate a up to 0.8W (24V*32mA = 0.77W). If the Q1 or BJT's heat is not properly dissipated or unable to dissipate the level of power, Q1 will be damaged, but XTR116 should survive.
Below is the simulated short circuit per the above scenario.
Will there be damage to the device if someone were to short a Vref or Vreg line to the Iin or Iret?
The short circuit conditions per the Vref and/or Vreg pins should survive over the operating temperature, see the absolute max. ratings table above. Even both pins are shorted to GND, the XTR116 will dissipate approx. 0.13W in total, not enough to damage the IC, which the Tj is rated at 165C.
If you have other questions, please let me know.
Best,
Raymond
