Title: SMD ID Hall effect
Post by: Wiljan on August 18, 2022, 07:51:14 am
Trying to find a Torqueedo remote shuttle control which does use a hall sensor as "Dead man switch" so if the magnet are removed it will stop.
The problem is the unit stops now and then while the magnet are still in place (can be moved like 10mm and still accepted so gauss but be fine) I then suspect the hall sensor itself to have a periodic error.

[attach=1]

So I'm looking for manufacturer / part number for a very small SMD effect sensor (North/South) non latching 6 pin
smd code "717 372 95"

Hope someone know where to find a cross table from SMD => part number

Perfect :-)

From datasheet:

YWW
LLL
NN

 Y = Last two digits of year of manufacture
 W = Week of manufacture
 L = Lot number
 N = Last two digits of device part number

NN= 95 and there is a match, how did you know it was AlLegro?

I searched for the keywords "霍尔" (Hall in Chinese) and "DFN" on taobao.com, and there were A1391SEHLT-T and A1393SEHLT-T on the first page of the search results.

Great idea, thank you for clarifying

This is one case where viewing this IC in the context of its surrounding ICs would have helped to determine if "717" was the date code.

Edit:

I tried a similar search with Google and found Allegro A1395SEHLT-T on the first page of results:
