Part Number: LM2903-Q1
my customer reported a destroyed LM2903-Q1 on a prototye board. We cannot investigate because the part is destroyed.I would like to help them to get an idea where to look in their application.
They have done impedance tests with the destroyed part:
pin8 (VCC) to pin4 (GND) -> 97 Ohmpin1 (OUT) to pin4 (GND) -> OLpin2 (IN-) to pin4 (GND) -> OLpin3 (IN+) to pin4 (GND) -> 43 Ohmpin8 (VCC) to pin1 (OUT) -> OLpin8 (VCC) to pin2 (IN-) -> OLpin8 (VCC) to pin3 (IN+) -> 97 Ohm
Can you confirm that such destruction and the measurements could be caused by overvoltage of VCC on the part?
