CBC5300 Overview
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 EnerChip 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 EnerChip 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 EnerChips, the charge controller will disconnect the boost converter from the EnerChips. This prevents the EnerChips from back-powering the boost converter in low input power conditions. The power...
