11. PPTC Characteristics & Behavior

Question.1

Tony selects a PPTC rated: I_hold = 0.5A, I_trip = 1A for a USB-powered device.
The circuit continuously draws 0.8A.
What will happen?

It will operate normally because 0.8A is below I_trip= 1A
It will immediately trip because 0.8A exceeds I_hold=0.5A
It may eventually trip because 0.8A exceeds the hold current
It will be heated but will keep operating as 0.8A is below I_trip= 1A
