FUNCTIONAL DESCRIPTION:
   The IL19006 Three Phase Power/Energy metering integrated circuit generates a pulse rate output, the frequency of which is proportional to the absolute power consumption. The IL19006 performs the calculations of active power.
   The method of calculation takes the power factor into account.
   Energy consumption is determined by the power measurement being integrated over time. The output of this universal three phase power/energy metering integrated circuit, is ideally suited for applications such as residential and industrial energy metering and control.
