Infineon Technologies AGTLI493DW2BWA0XTSA1Sensor de efecto Hall

The Infineon XENSIV™ TLI493D-W2BW 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 completely new design options.

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.

• TLI493D-W2BW A0
• TLI493D-W2BW A1
• TLI493D-W2BW A2
• TLI493D-W2BW A3
