The SS39ET, SS49E, SS59ET Linear Hall-effect Sensor ICs are small, versatile devices that are operated by the magnetic field from a permanent magnet or an electromagnet. The linear sourcing output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. The low voltage capability (as low as 2.7 Vdc) and reduced current consumption of only 6 mA (typical at 5 Vdc) help make this product energy efficient. The integrated circuitry features low noise output, which makes it unnecessary to use external filtering. It also includes thin film resistors to provide increased temperature stability and accuracy. These products interface with many electrical components without buffering and the thermally balanced integrated circuit provides stable operation over the full temperature range. These products are designed and manufactured for cost competitiveness. All packages can be supplied on tape for automated, lower-cost assembly. The SS39ET’s small footprint takes up less space on the PC board, typically allowing for more components.
“A magnetometer, sometimes also called Gaussmeter, measures the strength of the magnetic field. It is an essential tool to test the strength of permanent magnets and electromagnets and to understand the field shape of nontrivial magnet configurations. If it is …
