.. Preliminary Ener Chip™ EH CBC5300 Ener Chip™ EH Energy Harvesting Module Overview The Ener Chip EH CBC5300 is a self-contained Energy Harvesting power module in a 24-pin DIP configuration. The CBC5300 module is designed to accept a wide range of energy transducer inputs, store the harvested power, and deliver managed power to the target system. The purpose of this module is to enable system designers to quickly develop Energy Harvesting applications. A block diagram of the Ener Chip EH CBC5300 energy harvesting module is shown in Figure 1. Figure 2: Ener Chip EH Module - CBC5300 System Description Input Power Transducer Input Boost Converter Input/Output Pins Power Management The energy harvesting transducer (e.g. photovoltaic cell, piezoelectric material, thermoelectric converter, etc.) converts ambient energy into electrical energy. The output voltage of the energy harvesting transducer is often too low to charge the Ener Chip batteries and power the rest of the system directly, so a boost converter is used to boost the energy harvesting transducer voltage to the voltage needed to charge the Ener Chip and/or power the system. The charge control block continuously monitors the output of the boost converter. If the output of the boost converter falls below the voltage needed to charge the Ener Chips, the charge controller will disconnect the boost converter from the Ener Chips. This prevents the Ener Chips from back-powering the boost converter in low input power conditions. The power management block is used to protect the Ener Chips from discharging too deeply in low input power conditions or abnormally high current load conditions. The power management block also ensures that the load is powered up with a smooth power-on transition. The power management block has a control line (CHARGE) for indication to the system controller that the energy harvester is charging the Ener Chips. A control line input (BATOFF) is available for the controller to...
