3.3 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.
4 Circuit Module Physical Layouts and Bill of Materials
This section contains the board layout, bill of materials, and assembly drawings for the bq3060/bq29412
circuit module.
NOTE: The optional zener diode (D4) and resistor (R32) on the SYS PRES pin, which are only
required if SYS PRES has a chance to short to PACK+, are not available on REV. A EVM.
