I2C 인터페이스를 통하여 마이크로컨트롤러와 통신이 가능하며, 기존의 INA219 센서 3개를 INA3221 센서로 대치가 가능합니다.
아두이노의 I2C 인터페이스에 연결하여 사용합니다.
특징
Senses Bus Voltages From 0 V to 26 V.
Power-Supply Operation: 2.7 V to 5.5 V.
Programmable Alert and Warning Outputs.
The INA3221 monitors both shunt voltage drops and bus supply voltages.
In addition to having programmable conversion times and averaging modes for these signals.
The device is powered from a single 2.7-V to 5.5-V supply, and draws 350 µA (typ) of supply current.
The I2C- and SMBUS-compatible interface features four programmable addresses.
The INA3221 is specified over the operating temperature range of –40°C to +125°C.
The INA3221 is a three-channel, high-side current and bus voltage monitor with an I2C- and SMBUS-compatible interface.
The INA3221 offers both critical and warning alerts to detect multiple programmable out-of-range conditions for each channel.
