Infineon Technologies TLI493D-W2BW Low Power 3D Hall Sensor

Infineon Technologies TLI493D-W2BW Low Power 3D Hall Sensor features an I2C interface, enabling it to be easily configured by a microcontroller (MCU). The measurement data is provided in digital format to the MCU. The TLI493D-W2BW Sensor also provides the functionality to Wake-Up a sleeping system.

The TLI493D-W2BW measures the magnetic field in X, Y, and Z directions. Each X-, Y- and Z-Hall probe is connected sequentially to a multiplexer that is also connected to an Analog-to-Digital Converter (ADC). The TLI493D-W2BW also integrates an optional temperature sensor.

For each of the three magnetic channels (X/Y/Z), the Wake-Up function has an upper and lower comparison threshold. Each component of the applied field are compared to the lower and upper threshold. If one of the results is above or below these thresholds, an interrupt pulse /INT is generated. This is called a Wake-Up function. The sensor signals a certain field strength change to the microcontroller. As long as all components of the field stay within the envelope, no interrupt signal will be provided.

The Infineon Technologies TLI493D-W2BW Low-Power 3D Hall Sensor is offered in a tiny 1.13mm x 0.93mm x 0.59mm SG-WFWLB-5-2 package, enabling compact system designs.
