Infineon Technologies TLE5027CIE6747HAMA1

Overview

TLE5027CIE6747HAMA1 from Infineon Technologies is a highly accurate differential GMR-based speed and direction sensor for automotive powertrain applications. It detects ferromagnetic gear wheels or magnetic encoder wheels using two integrated GMR elements, delivers PWM output with programmable pulse widths (CW: 45 µs / CCW: 90 µs), operates from −40 °C to +175 °C junction temperature, and supports airgaps up to 3.5 mm with ferrite back-bias magnets.

For engineers reviewing the TLE5027CIE6747HAMA1 datasheet, TLE5027CIE6747HAMA1 pinout, TLE5027CIE6747HAMA1 application, or TLE5027CIE6747HAMA1 equivalent, key selection criteria include differential GMR sensitivity, adaptive hysteresis for vibration immunity, 3-wire PWM interface timing, reverse voltage protection at Vs, and integrated EMC capacitors (4.7 nF Q–GND, 47 nF Vs–GND).

Technical Context

The TLE5027CIE6747HAMA1 implements dual GMR sensing elements (iGMR1–iGMR5) in a differential configuration to reject common-mode field noise and detect edge transitions of gear teeth or pole pairs. Its hidden adaptive hysteresis algorithm dynamically adjusts switching thresholds during operation to maintain accuracy across airgap jumps and mechanical run-out.

Direction detection is derived from phase relationship between the two GMR signals and encoded as pulse-width modulated (PWM) output on the Q pin, with fixed timing profiles: 45 µs high for clockwise (CW) rotation and 90 µs high for counter-clockwise (CCW) rotation - matching the E6747 variant designation.

FAQ

What is the function of the integrated 47 nF and 4.7 nF capacitors?

The 47 nF capacitor between Vs and GND suppresses micro-cuts and ripple on the supply rail, while the 4.7 nF capacitor between Q and GND filters high-frequency noise on the PWM output. Both are factory-integrated to ensure repeatable EMC performance per ISO 11452-2/4 without requiring external components or layout tuning.

Does TLE5027CIE6747HAMA1 require an external magnet?

Yes - for gear wheel applications, a back-bias ferrite magnet is required to generate the in-plane magnetic field sensed by the dual GMR elements. For magnetic encoder wheels, the magnetized wheel itself provides the field; no external magnet is needed in that configuration.

How is direction information generated and verified?

Direction is computed by the on-chip digital core analyzing the phase relationship between the two differential GMR signals within the first three magnetic edges after startup. The result is encoded as fixed-duration PWM pulses (45 µs CW / 90 µs CCW) on the Q pin - verified per AEC-Q100 stress testing across temperature and vibration profiles.

Can this sensor operate without a microcontroller?

Yes - the TLE5027CIE6747HAMA1 is self-contained: it powers up, calibrates, detects direction, and outputs fully decoded PWM signals without any host processor or configuration. The 3-wire interface (Vs, GND, Q) allows direct connection to a timer-capture peripheral or comparator input.
