Hello,
Does anyone know manufacturer/type of this small ic, it is used with a (small permanent) magnet to detect open/closed of lid of machine. It is cracked and doesn't work anymore. 3 wires are connected. Please have a look at: http://145.18.160.21/612.jpg The first character appears to be a 'A' and also the number 612 seems complete. I looked at magnetic switches/sensors and hall effect ic's but found nothing appropriate. But if anyone recognizes the brand we are a step further!
Thanks, Mark
Check out Allegro.
Best regards, Spehro Pefhany

Yeah, you must be right. I already had a look at their website, and they do have a 612, a ATS612LSB/G, but physical appearance is very different and 4 pins instead of three. But I will crawl through the archives now I know the brand for sure (but didn't find it yet)
Thanks, Mark
It looks to be a hall effect sensor from your description. I expect you could replace it with any generic equivalent. The pins will be power, ground and output (possibly open collector ). You can determine if it needs an open collector output by examining the circuitry it feeds.

If the product is more than a few years old it might be obsolete, and they probably have a functional replacement.

FWIW,
The "E" suffix appears to designate an operating temperature range of
-40°C to +85°C.
Allegro have an A3144E part, but I don't know if it is anything like yours.
This site looks interesting, but I don't understand Chinese:
It has several Hall effect sensors including the A44E, A3144E, and WY44EUA.
