Testing Fuse-Blowing Circuit
To prevent the loss of board functionality during the fuse-blowing test, the actual chemical fuse is not
provided in the circuit. FET Q3 drives TP5 low if a fuse-blow condition occurs (a pull-up at TP5 is
required); so, monitoring TP5 can be used to test this condition.
