UCC27511: OUTL absolute max voltage

Part Number: UCC27511

Hi Guys

Our customer is using our UCC27511 as low side mosfet drivers. But about the system test, we found sometimes there is -2.4V at OUTL pin.

Please see below waveform:

CH4: Pin3 to GND. you can see there is -2.4V between pin3 to GND. and pulse time is around 4.4ns.

I also see that our absolute max negtive voltage at OUTL pin is -2V and less than 200ns in our datasheet. But could you help evaluate whether there is any risk about customer's application? how do we optimize our application to make it less?

Thanks
