TLI493D-W2BW A3
XENSIV™ - TLI493D-W2BW A3 dedicated for extremely space-critical applications such as BLDC commutation in micromotors or control elements
Infineon’s TLI493D-W2BW magnetic 3D sensor combines high-accuracy magnetic field measurements with an extremely compact footprint and exceptionally low power consumption (min. 7 nA). This sensor opens up a host of exciting new use cases including innovative human-machine interfaces in the form of industrial joysticks, ergonomic pushbuttons on domestic appliances and highly precise position control in robotics.
Due to the extremely small housing and the low current consumption, the TLI493D sensors are also suitable for use in applications that have not yet used magnetic sensors, e.g. as a replacement for potentiometers and optical solutions. Due to the contactless position determinations and a high temperature stability of the magnetic response values, smaller, more precise and more robust system concepts can be realized. A two-wire standard I2C interface enables fast communication, bus mode use, and two-way communication between sensor and microcontroller. Infineon's 3D magnetic sensors are ROHS compliant and qualified according to JEDEC JESD47, ensuring that customer systems meet the highest quality standards and various environmental regulations.
TLI493D-W2BW is available in 4 different variants ending with A0, A1, A2 or A3. The underlying feature is the so called Bus mode configuration of this device. It’s possible to connect up to 4 sensors to one I²C bus. The specific addressing is then done via 4 different variants.
