The INA219AIDR is a high-side bi-directional zero-drift Current Shunt and Power Monitor with an I2C- or SMBUS-compatible interface. The device monitors both shunt voltage drop and bus supply voltage, with programmable conversion times and filtering. A programmable calibration value, combined with an internal multiplier, enables direct readouts of current in amperes. An additional multiplying register calculates power in watts. The I2C- or SMBUS-compatible interface features 16 programmable addresses. The INA219 senses across shunts on buses that can vary from 0 to 26V. The device uses a single 3 to 5.5V supply, drawing a maximum of 1mA of supply current.
