Hi,
my customer is using LM5060 to drive a high side switch to connect/disconnect the power source to a load(resistor).
The resistor below highlilghted is 10k not 3k. Timer is left floating.
Vout is connected to the resistor load through 2m cable, when we turn off the MOSFETs at overcurrent condition, the waveform is as below:
yellow- Vout to GND, purple- Vin to GND, green- GATE to GND.
We can see that there is negative voltage appearing on Vout(-4V max), we guess it's caused by the long cable that add inductance to the load.
-4V exceeds the absolutely maximum voltage rating in datasheet. How could we solve such problem?
