Infineon Technologies AG will expand its XENSIV™ 3D magnetic sensor family TLx493D. At its in-house digital trade show “Virtual Sensor Experience”, the chipmaker will present a new device for industrial and consumer applications: the TLI493D-W2BW. It uses the latest 3D Hall generation from Infineon and is housed in an extremely small wafer-level package. With an 87 percent smaller footprint and 46 percent less height than previous comparable products, the sensor opens up new design options.
Due to the small WLB-5 package (1.13 mm x 0.93 mm x 0.59 mm) and its low current consumption of 7 nA in power-down mode, the new magnetic sensor is also suitable for use in applications that previously used resistor-based or optical solutions. Magnetic sensors offer numerous advantages here, such as their high accuracy or robustness against dust and moisture. In addition, magnetic sensors are easier to assemble and offer more design options.
In particular, the low height of the TLI493D-W2BW is helpful in extremely space-critical applications such as BLDC commutation in micromotors or control elements such as joysticks or game consoles. It enables designs with double-sided PCBs or positioning of the sensor between two PCBs. This allows optimal use of the available space; for example, additional components can be placed above the sensor.
