The SS449A is a useful device to measure magnetic flux density. It is a solid-state Hall Effect magnetic switch that consists of a balanced pair of Hall plates with an insulated gate FET in between. This unit is designed to measure flux density over a broad range of both linear and non-linear ranges. When exposed to a varying magnetic field, the Hall cells produce voltages proportional to the flux density. These voltages modulate the gate FET operating current. The SS449A can transfer the magnetic field values to minimal voltage outputs that produce a linear response over a wide range.
Performance
The SS449A is designed to maintain its accuracy independent of temperature and supply voltage. Its linearity remains strong regardless of the temperature or supply voltage. Additionally, this device is able to maintain its accuracy even when exposed to strong ambient magnetic fields. Its linearity and accuracy are further enhanced by its high common-mode rejection.
Applications
The SS449A is used in applications ranging from automotive control to robotics to security systems. In automotive applications, it can be used to measure the presence of a magnetic field and convert it to an output voltage that can be interpreted as an on/off signal that is independent of temperature and power supply voltage. In robotics, the SS449A can provide reliable and repeatable position measurements with minimal drift over its operating range. Finally, in security systems, the SS449A can be used to detect the presence of a magnetic field as an indication of a breach or tampering.
Working Principle
The SS449A uses Hall Effect sensing technology to measure magnetic fields. The device consists of two balanced Hall plates that are positioned between the insulated gate FET. When a magnetic field is present, each plate creates a voltage that is proportional to the field strength. This voltage modulates the gate FET’s operating current, which creates a voltage output signal that is directly proportional to the magnetic field strength. The output voltage of the device is then processed and converted into a signal that can be interpreted by a control system.
Conclusion
The SS449A is a solid-state Hall Effect magnetic switch ideal for sensing magnetic fields in automotive, robotic, and security applications. Its design ensures its accuracy and linearity over a wide temperature and voltage range while providing excellent common-mode rejection. The device works by detecting a magnetic field and generating a proportional voltage to modulate the gate FET’s operating current. These characteristics make the SS449A a reliable and repeatable magnetic field measure and a trusted switch for many applications.
