A3221 Triple-Channel Shunt Current & Voltage Sensor Board – Power Supply Monitor

Ang INA3221 ay isang triple-channel, high-side current at bus voltage monitor na idinisenyo para sa tumpak na pagsubaybay sa power-supply. Sinusukat nito ang parehong shunt voltage drops at bus supply voltages sa tatlong independent na channel, at nakikipag-ugnayan sa pamamagitan ng isang I²C- at SMBUS-compatible interface.

Gamit ang programmable conversion times at averaging modes, nagbibigay ang INA3221 ng flexible na configuration sa pagsukat. Kasama rin dito ang programmable critical at warning alerts upang matukoy ang iba't ibang out-of-range na kondisyon sa bawat channel, na sumusuporta sa maaasahang pagsubaybay at proteksyon ng system.

Nakaka-sense ang device ng current sa mga bus na may range mula 0 V hanggang 26 V at gumagana sa isang single 2.7 V hanggang 5.5 V supply, na kumokonsumo ng 350 µA (typical). Ito ay espesipikong ginawa para gumana sa malawak na temperature range na –40°C hanggang +125°C at sumusuporta sa apat na programmable I²C address para sa system integration.
