DESCRIPTION
The L4620 is an integratedcircuit, designedfor 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 attenuationexceedesan internal threshold- sensortip outsidethe liquidor liquid temperaturehigherthana determinedvalue- a squarewave alarm output indicates an unsufficient liquid condition.Ifthe liquidlevelisrestoredbeforetheend of a delay time the alarm is not activated.

■ DRIVES DIRECTLY 300 mA ALARM LOAD
■ PROGRAMMABLE INPUT POLARITY TO ACTIVATE THE OUTPUT STAGE
■ PROGRAMMABLE DELAY TIME
■ PROGRAMMABLE OUTPUT DUTY CYCLE
■ OUTPUT SHORT CIRCUIT PROTECTION
■ OVERVOLTAGEAND THERMAL PROTECTION
