L4620 LIQUID LEVEL ALARM

The L4620 is an integrated circuit, designed for the liquid level control in automotive applications. The liquid level is indicated by an attenuation between transmitted and received signal across a sensor tip in the lquid. If the attenuation exceedes an internal threshold- sensortip outsidethe liqu.
