XENSIV™ - TLE493D-A2B6 3D magnetic sensor with I2C Interface for automotive low power applications
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.
Summary of Features
3D magnetic flux density sensing of ±160mT
Programmable flux resolution down to 65µT (typ.)
X-Y angular measurement mode
Power down mode with 7nA (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 = 2.8V…3.5V
Triggering by external µC possible via I2C protocol
Interrupt signal to indicate a valid measurement to the microcontroller
Benefits
Component reduction due to 3D magnetic measurement principle
Wide application range addressable due to high flexibility
Platform adaptability due to device configurability
Disturbance of smaller stray fields are neglectable compared to the high magnetic flux measurement rang
Potential Applications
Gear stick position
Control elements in the top column module and multi function steering wheel
Multi function knobs
Pedal/valve position sensing
Applications
Automotive LED lighting systems
Diesel direct injection
General purpose motor drive - variating frequency and voltage
Industrial automation
