ADP5091ACPZ-1-R7

ADP5091 is an intelligent, integrated energy harvesting, ultralow power management unit (PMU) solutions that convert dc power from PV cells or TEGs. These devices charge storage elements such as rechargeable Li-ion batteries, thin film batteries, super capacitors, or conventional capacitors, and power up small electronic devices and battery free systems. It provides efficient conversion of the harvested limited power from a 6µW to 600mW range with sub microwatt operation losses. With the internal cold start circuit, the regulator can start operating at an input voltage as low as 380mV. After cold start-up, the regulator is functional at an input voltage range of 0.08V to 3.3V. It is used in application such as photovoltaic (PV) cell energy harvesting, thermoelectric generators (TEGs) energy harvesting, industrial monitoring, self powered wireless sensor devices, portable and wearable devices with energy harvesting etc.
