Magnetic Sensors - Switches make use of solid state technology integrated into a robust package for applications demanding high-reliability sensing. The TLV4906KFTSA1 magnetic sensor utilizes tunneling magnetoresistance (TMR) to provide highly accurate, reliable detection in a variety of industrial and automotive applications. The device is ideal for use with high-demand systems in need of low current operation and superior long-term reliability.

The TLV4906KFTSA1 is a highly sensitive low power Hall effect sensor designed to detect small changes in magnetic fields. It is a single-chip solution that features a high-gain fast-timing amplifier enabling high-reliability sensing in a variety of automotive and industrial applications. The device uses spintronics, or “spin” electronics, to detect magnetic fields with unprecedented accuracy. The solid state construction of the chip ensures that noise signals are virtually eliminated, resulting in significantly improved signal-to-noise ratios.

In general, the TLV4906KFTSA1 can detect up to a 10-gauss change with accuracy and speed. It features a built-in amplifier circuit with a low noise figure and adjustable threshold and output levels to ensure reliable results in applications. The integrated circuit includes a demagnetizing circuit to allow it to automatically adjust its sensing if needed. The integrated circuit also uses proprietary technology to reduce power consumption and improve performance.

The TLV4906KFTSA1 magnetic sensor detects magnetism in three different directions — in-plane, out-plane, and lateral. These measurements are used to control how the sensor\'s output signal is sent when a magnet is present. The device features a built-in timer to help eliminate false triggering and a built-in temperature-sensing circuit which can be set up to monitor the temperature of the sensor and its environment. The device is also available in multiple package options for convenient installation.

The working principle of the TLV4906KFTSA1 is based on tunneling magnetoresistance (TMR). This is an effect which occurs when an external magnetic field induces an electrical resistance change in a magnetic film. The device contains a Hall-effect sensor which responds to near-field changes in the magnetic field. As the magnetic field changes, the device outputs a proportional voltage response based on the direction and magnitude of the change. The output voltage level is regulated by the integrated bit comparator circuit.

The TLV4906KFTSA1 is applicable to a variety of automotive and industrial applications including automotive styling, functional safety, and wearables. The device also has several automated pre-programmed safety features to ensure that the parameters remain within operational limits. The device is designed to meet harsh environmental demands and is suitable for a wide range of temperatures, humidities, and shock/vibration levels. The device is widely used in automotive applications such as side-view mirrors, steering wheel and seat memory modules, and door lock controllers. It is also especially useful in industrial applications such as motor controllers, navigation systems, and proximity sensing systems.
