I have a customer who is using the SN65HVD23 between a Control PC and a radar transmitter. The device output is failing to the PC and in a permanent low state when failure occurs.
Customer called to report that the chip is burning out 1 every 40 hours. The customer believes something external on the load side may have lead to its destruction. My question pertains to the likely cause of these failures… The customer expecting a load transient, but wanted to be sure that the chip is protected from an over-current output condition (which was communicated to the customer) and would like to know how long the device can handle an over-voltage event and how high a voltage before damaging the device.
