Other Parts Discussed in Thread: LM5051
The PIM_VRTN input is 54V, and the gate pin drives 4 mosfets.
When the normal load is 20A, LM5051 works normally. When the load current increases to 25A, LM5051 VCC is short-circuited to gnd.
I want to confirm
1. Is the TVS inside the VCC damaged?
2. What is the maximum current that TVS can withstand?
3. In addition, how much driving current can the gate output?
