Infineon Technologies TLE493D Low Power 3D Hall Sensors
Infineon Technologies TLE493D Low Power 3D Hall Effect Sensors offer accurate three dimensional sensing with extremely low-power consumption. The TLE493D are housed in a small 6-pin package and provide direct measurement of the x-, y-, and z components of a magnetic field. The sensors can be configured by a microcontroller and measurement data is provided in digital format to the microcontroller. The microcontroller acts as master and provides test functions with the capability to wake up a sleeping system.
Features
- 3D magnetic flux density sensing of ±160mT
- Programmable flux resolution down to 65µT (typical)
- X-Y angular measurement mode
- Diagnostic measurements to check digital parts, analog parts, and Hall probe of the sensor
- Power down mode with 7nA (typical) 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= 2.8V to 3.5V
- Supports triggering by external µC via I2C protocol
- Interrupt signal to indicate a valid measurement to the microcontroller
Applications
- Gear stick position
- Control elements in the top column module and multi function steering wheel
- Multi function knobs
- Pedal/valve position sensing
