Preliminary
EnerChip CC CBC3105
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.
Figure 7: CBC3105 Typical Circuit for Mode 2 Operation
EnerChip charging and backup power switchover threshold for 2.5 to 5.5 volt operation is selected by changing
the value of R2 (see Figure 7). To determine the backup switchover point, set the value of R1 to 200k ? and
choose the value of R2 according to Figure 8. For example, to set a 3.0V trip point: If R1=200 k ? then R2 = R1
x 0.72 = 144k ? . Figure 7 shows a Mode 2 circuit with standard value resistors of 200k ? and 143k ? .
To determine the backup switchover hysteresis for Mode 2 operation, use Figure 9.
