Subsection #742
Von Maximilian Seesslen vor 19 Tagen aktualisiert
The inrush is super high and can lead to triggered fuse. Its bad for power supply and MOSFET.
To limit current to 2A and assuming R_Load is 0 Ohm, 72 Watt MOSFET is needed.
So the DI077P06D1-DIO is not overdesigned with its 110 Watt.
Im normalbetrieb (VGS=-4,5): V_MOSFET = 0,017 Ohm * 2 A = 0,034 V
0,034 V * 2 A = 0,068 W
