Simple fused digital switching
Design files: -- Schematic -- Fusion360 native project files -- 3D model .obj -- electrical library for custom parts -- Dimensional drawing
Manufacturing files: -- Gerbers for PCB fab -- BOM for ordering from Digikey
Input voltage range: 2.5-20V Maxiumum output voltage limit: 80V Gate capacitance: 4.5uF max
Connect multiple modules together with a bus bar for a custom fusebox. Ground the control pin to turn on, or bypass the MOSFET with 14awg wire for constant power
For trouble-free operation, it is highly recommended that you protect the Module's FET with a TVS diode like MPN: TP6KE22A or SM30T18AY
Inductive loads like relays without flyback diodes can cause damaging voltage spikes when shut off
Increase pad size for easier soldering (COMPLETE)
Built-in slew rate limiting resistor on gate Locking/secure connector for gate control line Built-in TVS w/ parallel ground bus bar
