What are the key features of SPV1050-WST?
- Embedded Maximum Power Point Tracking (MPPT) algorithm continuously optimizes energy extraction from solar panels and thermoelectric generators
- Ultra-low power operation with quiescent current typically under 10 µA, extending battery life in energy-constrained IoT nodes
- Dual integrated LDO regulators provide regulated output voltages for simultaneous powering of MCU and RF transceiver loads
- Single-channel linear battery charger supports Li-ion and LiPo cells with programmable charge current and termination thresholds
What is SPV1050-WST used for?
The SPV1050-WST is used in self-powered IoT sensor nodes and wireless monitoring systems that harvest energy from indoor or outdoor photovoltaic cells in the range of 10 µW to 100 mW. Its embedded MPPT ensures maximum energy extraction even under low-light or variable irradiance conditions typical of building automation and environmental monitoring deployments. The dual LDO outputs allow simultaneous operation of a low-power MCU and a BLE or Zigbee radio from a single harvested energy source with a rechargeable battery buffer.
