S-5711A

Rev.2.4_00 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, SOT23-3 packages. Also, the S-5711A Series is the most suitable for portable devices due to the low current consumption.

Direction of applied magnetic flux and position of Hall sensor Rev.2.4_00 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.

Basic operation HALL IC S-5711A Series 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”. *1.

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.
