Kako meriti mikroAmp/nanoAmp potrošnju
#43
npejcic

setio sam se na INA219
http://www.ti.com/lit/ds/symlink/ina219.pdf

monitoring struje na Shunt-u, napona Bus ulaza do Shunt-a, I2C ili SBUS interface, interni registar radi i kalkulaciju Power, pa imaš sve več dostupno kao DATA

EDIT:
TI familija Digital interface monitorirnga

Možda odabrati takvog sa High accurancy i po mogučnosti sa integrisanim Shuntom, INA260,
http://www.ti.com/lit/ds/symlink/ina260.pdf
jeste skuplje, ali je sve to več odradjeno u ICju
i ne preko dosta veče površine na PCBju, zbog interferenci i transformatorskog preslikavanja i unašanja dodatnog errora...
