Power LEDs

Stimuli: Plug in in USB-C upstream * Expected: LED +5V UPSTREAM
Stimuli: Plug in 5V barrel jack * Expected: LED +5V PROTECTED

Voltage slew rate

Rationale: Verify slew rate
Setup: Connect scope on GND and 5V PROTECTED
Stimuli: Plug in 5V barrel jack
- Expected linear slew rate from 0 to 5V
- 2ms calculated
- 200ms measured…

Overvoltage protection

Precondition: 5V barrel jack connected
Setup: Connect scope on GND and 5V PROTECTED
Stimuli: Shorten GND and 5V PROTECTED
- Expected:
  - LED +5V PROTECTED goes off
  - Voltage +5V PROTECTED stays on 0V
Stimuly: 5V barrel jack unplug and plug
- Expected:
  - LED +5V PROTECTED goes back on again
  - Voltage +5V PROTECTED goes back to 5V
