Infineon Technologies 3D hall sensors - TLE493D

The TLE493D-P2B6 is a magnetic 3D sensor enabled by new and improved HTM test equipment used in qualification. It has improved technical performance of TLE493D-W2B6.

Key features

• 3D (X, Y, Z) magnetic flux density sensing of ±160 mT
• Programmable flux resolution down to 65 µT (typ.)
• X-Y angular measurement mode
• Diagnostic measurements to check digital parts, analog parts and Hall probe of the sensor

Additional features

• Wake Up function and Power-down mode with 7 nA (typ.) power consumption
• 12-bit data resolution for each measurement direction plus 10-bit temperature sensor
• Variable update frequencies and power modes (configurable during operation)
• Temperature range Tj = -40 °C to 125 °C
• Supply voltage range = 2.8 V to 3.5 V
• Triggering by external MCU is possible via I2C protocol
• Interrupt signal to indicate a valid measurement to the microcontroller

Additional benefits

• Component reduction due to 3D magnetic measurement principle
• Wide application range addressable due to high flexibility
• Platform adaptability due to device configurability
• Supporting functional safety by means of integrated diagnostics
• Very low system power consumption due to Wake-Up mode resulting in extended battery runtime
• Disturbance of smaller stray fields are neglectable compared to the high magnetic flux measurement range

Applications

• Gear stick position
• Multi-function knobs
• Pedal/valve position sensing
• Control elements in the top column module
• Multi-function steering wheel
