These include backup power sources for real-time clocks, microcontrollers, and memory chips to maintain operation during periods when main power is interrupted. EnerChips are also well suited as energy storage devices for wireless sensor nodes where energy is harvested from ambient power sources. The integrated battery and power management circuitry included in the EnerChip CC products provides supply voltage threshold detection, an automatic energy storage switchover function, and EnerChip charge-discharge control circuitry – all in a compact surface mount package that includes the EnerChip storage device. Figure 1 depicts the EnerChip CC surface mount package and the CBC-EVAL-10 development module designed for evaluating the EnerChip CC devices in energy harvesting applications.
