Overview
® L4620 LIQUID LEVEL ALARM .
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 OVERVOLTAGE AND THERMAL PROTECTION Minidip ORDERING NUMBER : L4620 DESCRIPTION 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 liquid or liquid temperaturehigher than a determinedvalue - a squarewave alarm output indicates an unsu...
