nRF52832 series IC is used to BLE interface of an energy harvesting platform. BLE communication module is designed to charge main cacacitor to upper limit and then generates an interrupt to MCU to enable the BLE IC. If the stored energy is getting low another interrupt is generated to inform MCU to disable the IC. Interrupts are generated by ultra low power comparators. Interrupt generating voltage levels are adjustable by digital resistor.
