HALL IC
S-5711A Series
The S-5711A Series, developed by CMOS technology, is a Hall IC with a
high-sensitivity and operates on a low current.
The output voltage changes when the S-5711A Series detects the intensity
level of flux density. Using the S-5711A Series with a magnet makes it
possible to detect the open/close state in various devices.
High-density mounting is possible by using the super-small SNT-4A, SOT-
23-3 packages. Also, the S-5711A Series is the most suitable for portable
devices due to the low current consumption.

2. Basic operation
The S-5711A Series changes the output voltage level (VOUT) according to the level of the magnetic flux density (north
or south pole) applied by a magnet.
The following explains the operation when the magnetism detection logic is active “L”.
(1) Products with detection of both poles
When the magnetic flux density vertical to the marking surface exceeds BOPN or BOPS after the south or north pole
of a magnet is moved closer to the marking surface of the S-5711A Series, VOUT changes from “H” to “L”. When
the south or north pole of a magnet is moved further away from the marking surface of the S-5711A Series and
the magnetic flux density is lower than BRPN or BRPS, VOUT changes from “L” to “H”.
(2) Products with detection of south pole
When the magnetic flux density vertical to the marking surface exceeds BOPS after the south pole of a magnet is
moved closer to the marking surface of the S-5711A Series, VOUT changes from “H” to “L”. When the south pole
of a magnet is moved further away from the marking surface of the S-5711A Series and the magnetic flux density
is lower than BRPS, VOUT changes from “L” to “H”.
(3) Products with detection of north pole*1
When the magnetic flux density vertical to the marking surface exceeds BOPN after the north pole of a magnet is
moved closer to the marking surface of the S-5711A Series, VOUT changes from “H” to “L”. When the north pole
of a magnet is moved further away from the marking surface of the S-5711A Series and the magnetic flux density
is lower than BRPN, VOUT changes from “L” to “H”.
