The INA2227 device is a dual channel 16-bit digital current monitor with an I2C/SMBus-compatible interface that is compliant with digital bus voltages from 1.2V to 5V. The device monitors the voltage across an external sense resistor and reports values for shunt voltage, bus voltage, current, power, and energy for each channel.

The INA2227 features programmable ADC conversion times and averaging that is common for all channels. Each channel has a programmable calibration value with an internal multiplier that enables direct readouts of current in amperes, power in watts, and energy in joules. Each channel has a dedicated VBUS pin to monitor the bus voltage and can alert on overcurrent and undercurrent conditions, as well as on overvoltage and undervoltage conditions.High input impedance while in current measurement mode allows use of larger current sense resistors needed to measure small value system currents.

The INA2227 senses current on common-mode bus voltages that can vary from –0.3V to 48V, independent of the supply voltage. The device operates from a single 1.7V to 5.5V supply, drawing a typical supply current of 400µA in normal operation. The device can be placed in a low-power standby mode where the typical operating current is 2.5µA and can be fully disabled using the enable pin to achieve an supply current less than 50nA. The device is specified over the operating temperature range between –40°C and 125°C and features up to 16 programmable addresses.
