EM8500 PMIC with Energy Harvesting Capability

EM Microelectronics’ EM8500 power management controller (PMIC) is designed for efficient operation with a variety of DC harvesting sources including thermal electric generators (TEG) or photovoltaic (solar) sources in the µW to mW range. The EM8500 integrates a programmable maximum power point tracking (MPPT) controller to maximize harvesting efficiency.

The EM8500 is capable of operating with a variety of energy elements as re-chargeable batteries, super-capacitors, or conventional capacitors. When using a non-rechargeable battery, the EM8500’s onboard power management unit (PMU) offers a mechanism to extend battery life when assisted by a harvesting element. To perform granular power management of the application, the EM8500 integrates four independent supply outputs and a sleep mode offering the capability to switch off part or all the supplies.
