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.

The operating points are the values of magnetic flux density when the output voltage (VOUT) is inverted after the magnetic
flux density applied to the S-5711A Series by the magnet (N or S pole) is increased (the magnet is moved closer).
Even when the magnetic flux density exceeds BOPN or BOPS, VOUT retains the status.
*2. BRPN, BRPS : Release points
The release points are the values of magnetic flux density when the output voltage (VOUT) is inverted after the magnetic
flux density applied to the S-5711A Series by the magnet (N or S pole) is decreased (the magnet is moved further away).
Even when the magnetic flux density falls below BRPN or BRPS, VOUT retains the status.

Operation
1. Direction of applied magnetic flux and position of Hall sensor
The S-5711A Series detects the flux density which is vertical to the marking surface.
In products with detection of both poles, the output voltage (VOUT) is inverted when the south or north pole is moved
closer to the marking surface.
In products with detection of the south pole, the output voltage (VOUT) is inverted when the south pole is moved closer to
the marking surface.
In products with detection of the north pole, the output voltage (VOUT) is inverted when the north pole is moved closer to
the marking surface.
Figures 10 and 11 show the direction in which magnetic flux is being applied.

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”.

3. Time dependency in the current consumption
The S-5711A Series performs the intermittent operation. The S-5711A Series operates with low current consumption
due to repeating the sleep mode (50 ms typ.) and the awake mode (130 µs typ.).
Figure 17 shows the time dependency in the current consumption.

Precautions
• If the impedance of the power supply is high, the IC may malfunction due to a supply voltage drop caused by through-
type current. Take care with the pattern wiring to ensure that the impedance of the power supply is low.
• Note that the IC may malfunction if the power supply voltage rapidly changes.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• Large stress on this IC may affect on the magnetic characteristics. Avoid large stress which is caused by bend and
distortion during mounting the IC on a board or handle after mounting.
• When designing for mass production using an application circuit described herein, the product deviation and
temperature characteristics of the external parts should be taken into consideration. SII shall not bear any responsibility
for patent infringements related to products using the circuits described herein.
• SII claims no responsibility for any disputes arising out of or in connection with any infringement by products including
this IC of patents owned by a third party.
