EnerChip CC CBC3112
Mode 1 Operation
For use in 3.3 volt systems. The VMODE pin should be tied directly to GND, as shown in Figure 6. This will set the
switchover threshold at approximately 3.0 volts.

Mode 2 Operation
Figure 7 shows the circuitry for user-selectable switchover threshold to a value between 2.5 and 5.0 volts. Use
Figure 8 to determine the value of R1. To determine the amount of hysteresis from the EnerChip switchover
threshold, use Figure 9.
