The sensor has been specially designed to be robust against noise and vibration in calibrated and un-calibrated mode. High sensitivity and accuracy combined with its wide operational temperature range makes the sensor ideally suited for the harsh automotive requirements. It comes in a three pin package for the supply voltage and an open drain output. Infineon also offers customers the possibility to order sensors with already attached back bias magnets (TLE4957CB-2 E6747). 1.2 • • • • • • • • • • • • • • Features Hall based principle High sensitivity High robustness against vibration Adaptive hysteresis Large operating airgap Single chip solution Digital output signal (voltage interface) Two-wire and three-wire configuration possible Wide operating temperature ranges Short-circuit and over temperature protection of output High resistance to Piezo effects South and north pole pre-induction possible Integrated back bias magnet as an option Module style package with two integrated capacitors: – 4.7 nF between Q and GND – 47 nF between VS and GND: Needed for micro cuts in power supply Type Order Code Marking Package TLE4957C-2 E6747 SP000649296 57D82 PG-SSO-3-92 TLE4957CB-2 E6747 SP001056526 957D00 PG-SSOM-3-11 Product Information 3 2013-10-16 TLE4957Cx-2 E6747 Dynamic Differential Hall Effect Sensor Functional Description 2 Functional Description 2.1 General The TLE4957Cx-2 E6747 detects the motion and position of ferromagnetics and permanent magnet structures by measuring the differential flux density of the magnetic field. To detect ferromagnetic objects the magnetic field must be provided by a back biasing permanent magnet (south or north pole of the magnet attached to the rear unmarked side of the IC package). 2.2 Pin Configuration Data Code S 0015 Marking 4100 R Symbol Function VS Supply Voltage GND Ground Q Open Drain Output VS GND Q Figure 2-1 Sensor assembly Line 1 VS 4 C Q 2 GND CF 3 470 nF VS RL VSIGNAL RS Sensor Mainframe For example: RL = 330 Ω RS = 120 Ω Figure 2-2 Two wire configuration Rp 1 VS 4 C 2 Q GND CF 3 470 nF Line VS RL VSIGNAL 4.7 nF 4.7 nF Sensor Mainframe For example: RL = 330 Ω Rp = 0… 330 Ω Figure 2-3 Three wire configuration Product Information 4 2013-10-16 TLE4957Cx-2 E6747 Dynamic Differential Hall Effect Sensor Specification 3 Specification 3.1 Operating Range Table 3-1 Operating Range Parameter Symbol Values Min.
