INA219BIDCNT

The INA219BIDCNT is a high-side bi-directional zero-drift current shunt and Power Monitor with an I²C interface. The INA219 monitors both shunt drop and supply voltage with programmable conversion times and filtering. A programmable calibration value, combined with an internal multiplier, enables direct readouts in amperes. An additional multiplying register calculates power in watts. The I²C interface features 16 programmable addresses. The monitor senses across shunts on buses that can vary from 0V to 26V. The device uses a single +3 to +5.5V supply, drawing a maximum of 1mA of supply current.
