HI!
We have from time to time defect High Side Driver. Most of the defects occur after the first few power on cycles.
The High Side Driver and the RGND Resistor (120Ohm) gets really hot. The resistance between GND and the Status Pin is then much lower around 160Ohm to 2kOhm instead of 12kOhm.
Might it be a Problem when there is only the 24V Power Supply and the Status / IN Pin has no reference Voltage?
There are cases when the 5V comes later or not. Does this destroy the internal Logic Circuit?
Did somebody had some similar defects?
Any help is much appreciated.
THX
