TLE493D-A2B6

Infineon´s TLE493D-A2B6 is designed for all kinds of sensing applications, especially in the automotive area such as multi function steering wheel.It measures the magnetic field in X, Y and Z direction. Each X-, Y- and Z-Hall probe is connected sequentially to a multiplexer, which is then connected to an Analog to Digital Converter (ADC). Optional, the temperature (default = activated) can be determined as well after the three Hall channels.

Key Features

• 3D magnetic flux density sensing of ±160 mT.
• Programmable flux resolution down to 65 µT (typ.).
• X-Y angular measurement mode
• 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…125°C, supply voltage range = 2.8 V…3.5 V
• Triggering by external µC possible via I2C protocol
• Interrupt signal to indicate a valid measurement to the microcontroller

Application

• The TLE493D-A2B6 is designed for all kinds of sensing applications, including the following:
• Gear stick position
• Control elements in the top column module and multi function steering wheel
• Multi function knobs
• Pedal/valve position sensing
