Product Description
ST Microelectronics # L4620. An integrated circuit designed for the liquid level control in automotive applications. The liquid level is determined by the attenuation between transmitted and received signals across a sensor tip in the liquid. If the attenuation exceeds an internal threshold - sensor tip outside the liquid or liquid temperature higher than a determined value – a square-wave alarm output indicates an insufficient liquid condition. Internal circuits prevent spurious indications, and a latch keeps the alarm activated until the supply voltage is switched off. 8-pin dip package. Spec. sheet available on our web site.
Spec sheet available in PDF format.

Have not used it yet!

Reviewer: from Houston, TX USA

I ordered 2-3 recently. They are cheap enough!
I plan to put it on a bread board very soon. I will place it under the water heater (on a mini-
bread board), in case of a leak! KD5BIH
