Functional Block Diagram
The EnerChip CC internal schematic is shown in Figure 2. The input voltage from the power supply (V
applied to the charge pump, the control logic, and is compared to the user-set threshold as determined by the
voltage on V

output that, when low, indicates V
C
impedance of the EnerChip CC needs to be modified. The output impedance is dictated by 1/fC, where f is the
frequency of oscillation (typically 100kHz) and C is the capacitor value (typically 0.1µF). GND is system ground.
