Description:
Tunneling Magneto Resistive (iTMR) technology is offering high sensing sensitivity with a high output voltage so that no internal amplifier – thus the sensor can be connected directly to the microcontroller without any further amplification. In addition, iTMR technology shows a very low temperature drift reducing external calibration and compensation efforts. The iTMR technology is also well known for its low current consumption. With the TLE5501 products, Infineon is currently launching the first angle sensor products based on iTMR technology. TLE5501 is available in two versions.
The TLE5501 is a 360° TMR-based angle sensor that detects the orientation of a magnetic field. This is achieved by measuring sine and cosine angle components with Tunneling Magneto Resistance (TMR) elements. These raw signals (sine and cosine) are provided as a differential output signal and can directly be further processed within a micro controller. The large output voltage of the bridge renders any further signal amplification unnecessary.
Summary of Features:
Large output signals of up to 0.37 V/V for direct micro controller connection
Discrete bridge with differential sine and cosine output
Supply current: ~2 mA
Magnetic field range (20 mT to 100 mT)
Typ. angle error ~ 1.0 ° (overtemperature and lifetime)
Designed for Safety: 2 independent dual channel sensors
DSO-8 package
Automotive qualified Q100, Grade 0: TA = -40°C to 150°C (ambient temperature)
Target Applications:
Angular position sensing
Safety applications
Steering angle sensor
BLDC motor commutation
