SPV1050 - STMicroelectronics

SPV1050 Ultralow power energy harvester and battery charger

The SPV1050 is an ultra-low power and high-efficiency power manager embedding four MOSFETs for boost or buck-boost DC-DC converter and an additional transistor for the load connection/disconnection. An internal high accuracy MPPT algorithm can be used to maximize the power extracted from PV panel or TEG. The internal logic works to guarantee tight monitoring.
