Product Brief TLE5027C Highly accurate and sensitive differential speed sensor with direction detection for automotive powertrain and industrial applications Features The TLE5027 uses the giant magneto resistive (GMR) effect, which is by a factor >10 more sensitive compared to the Hall-effect. The TLE5027 detects the motion and Excellent sensitivity position of ferromagnetic magnet structures by measuring the change of the magnetic High jitter performance field induced by this structure, which can be a magnetic encoder wheel, ferromagnetic Direction detection gear wheel or any similar structure. In case of any non-encoder based application like Hidden adaptive algorithm gear wheels the magnetic field is generated by applying a specially optimized back Very large operating airgaps bias magnet to the sensor. As the GMR sensor measures the in plane components of Advanced performance by the magnetic field the sensor switches in phase with the edges of a tooth/gap pair of dynamic self calibration a gear wheel or north/south pole pair of a magnetic encoder. The very high sensitivity principle of the GMR effect enables the TLE5027 to measure very large airgaps with encoder Very low current consumption wheels or be back biased with excellent airgap performance using a low-cost ferrite 3-wire PWM voltage interface material for the magnet. Wide operating temperature ranges of -40C T +175C j The sensor has a fast start up time and the sensor switches with its hidden adaptive Reverse voltage protection hysteresis algorithm, which ensures high accuracy over airgap jumps, vibrations, run- at V -pin s out events ,etc. Within the first 3 magnetic edges after start up the sensor provides the High ESD robustness direction information, which is given as pulse width modulated output. Module style package with two integrated capacitors: TLE5027 is well suited for harsh environmental conditions prevalent in automotive or 4.7nF between Q and GND certain industrial applications by its wide temperature range as well as high ESD and 47nF between V and GND: s EMC robustness. In addition the TLE5027 provides the benefit of a very low current Required for micro cuts in consumption. With its features the TLE5027C is ideal for applications like todays crank- power supply and optimal shaft or transmission speed sensing in automotive or similar industrial applications. EMC robustness TLE5027 is perfectly suited for applications like: Gear wheel application with back bias magnet and magnetic encoder wheel application Magnet Wheel Gear Wheel GMR Sensor 1 GMR Sensor 2 GMR Sensor 1 GMR Sensor 2 Signal Signal Processing Processing Circuitry Permanent Magnet Circuitry S (N) N (S) Back Bias Magnet Encoder Wheels www.infineon.com/magnetic-sensorsProduct Brief TLE5027C Highly accurate and sensitive differential speed sensor with direction detection for automotive powertrain and industrial applications Block Diagram V S Supply Reset Core 5027 Min/Max Preamp.
