2.8 SuperCap

The LaunchPad is equipped with a 100mF super capacitor that can be used to supply power to VBAT. For the SuperCap to power the LFSS module, the jumper on J101 must be connected to VBAT and CAP. Enabling the Figure 2-5 allows the SuperCap to charge to VDD while making sure that the circuit switches off if VDD drops below VBAT. Note that enabling this circuit connects VBAT to VDD, even if the isolation jumper is not connected.
