Hello, I am configuring two LTC4359s in a diode ORing configuration with prioritization set by an MCU. I'm using two SIR680LDP-T1-RE3 as the switch FETs. See one side of the circuit below. I am running into a situation that Q1 becomes damaged. When there is no load, it always switches fine without damage. However, when I introduce a load and pull current through these FETs, then exercise the SHDN pin on the LTC4359 to switch it on/off, at some point Q1 becomes damaged. Q2 does not become damaged. I see from the datasheet that R5 is necessary to prevent parasitic oscillations, and I have it on there. I am also looking at the gate of Q1 and don't see any oscillation there.
Is there anything else that I can look at?
