STEVAL-ISV019V1, EVAL BRD, ENERGY HARVESTER/BATT CHARGER

Evaluation board based on the ultralow power energy harvester and battery charger SPV1050. The evaluation board implements the boost configuration of the DC-DC converter and has the purpose of enhancing the SPV1050 based applications development by testing the silicon performance thanks to many jumpers and test points and by helping to find out the best system configuration to make the SPV1050 device working at the most of efficiency. The STEVAL-ISV019V1 is optimized to harvest energy from PV panels supplying 0.5V <= VMP <= 2.5V and 30µA <= IMP <= 20mA. Charge a battery with 3.7V undervoltage protection threshold (VUVP) and 4.2V end of charge voltage threshold (VEOC). Typically used for WSN, HVAC, building and home automation, industrial control, access control, smart lighting, asset and livestock positioning and tracking, surveillance.

• First start-up at Vin = 500mV
• Input voltage working range from 150 mV <= Vin <= VEOC
• End of charge battery voltage VEOC = 4.25V
• Charge any battery chemistry including lithium based, NiMH, solid state thin film and supercapacitor
• Body area network, sportswear, fitness
