3. IC(INTERGRATED CIRCUIT)
IC has built in DIODE against overvoltage in PIN. Generally, except for internal circuit defects, IC defects can be
found,
By measuring the DIODE.
Forward Direction
Hundreds of ohms
Varying depending on IC but generally normal
Reverse Direction
Infinity in DIODE TEST MODE
* Defects have SHORT(0 ohm) for both forward and reverse direction
