Hi Team,
We have a design using the LM25066 for 12V hotswap (see schematic attached). We have one board where the gate drive is at a steady 7.5V resulting in P12V_BMC being at a steady 6V. VIN is at 12V and UVLO/EN is at 1.59V so the LM25066 should be fully on. Output P12_BMC to GND is normal resistance compared to a good board 500Ω, plus if the output was shorted I’d expect the LM25066 to completely turn off.
Any ideas on what could be wrong? Could it just be a faulty part?
