Product details

Overview

TLE5027CE6747HAMA1 from Infineon Technologies is a highly accurate differential GMR-based speed and direction sensor for automotive powertrain applications, featuring 45 µs CW / 90 µs CCW PWM output, -40°C to +175°C junction temperature range, reverse voltage protection at Vs, and operation with airgaps up to 3.5 mm using ferrite back-bias magnets in crankshaft or transmission speed sensing.

For engineers reviewing the TLE5027CE6747HAMA1 datasheet, TLE5027CE6747HAMA1 pinout, TLE5027CE6747HAMA1 application, or TLE5027CE6747HAMA1 equivalent, key selection criteria include PWM pulse width asymmetry (CW/CCW), adaptive hysteresis behavior under vibration/run-out, GMR sensor pair configuration, integrated EMC capacitors (4.7 nF Q–GND, 47 nF Vs–GND), and PG-SSO-3-92 package thermal performance in under-hood environments.

Technical Context

The TLE5027CE6747HAMA1 implements dual GMR bridge pairs (iGMR1–iGMR5) measuring in-plane magnetic field components to detect edge transitions of ferromagnetic gear teeth or encoder poles. Its hidden adaptive hysteresis algorithm dynamically adjusts switching thresholds during airgap jumps or mechanical run-out.

Direction detection is embedded in the first three magnetic edges after power-up and encoded as asymmetric PWM duty cycle (45 µs high for CW, 90 µs high for CCW). Signal processing includes low-pass filtering, min/max tracking, and digital core reset synchronization - all operating from a single 3-wire supply (Vs, GND, Q).

Key Specifications

Parameter	Value and Actual Design Meaning
Output Interface	3-wire PWM voltage output (Vs, GND, Q); no external pull-up required
CW Pulse Width	45 µs high-time - enables precise clockwise rotation timing in crankshaft position decoding
CCW Pulse Width	90 µs high-time - provides unambiguous counter-clockwise direction discrimination
Operating Temperature	-40°C ≤ Tj ≤ +175°C - supports placement near hot engine blocks without derating
Airgap Capability	Up to 3.5 mm with ferrite back-bias magnet - reduces mechanical tolerance constraints in transmission assemblies
ESD Robustness	±8 kV HBM - sustains handling and assembly without additional protection circuitry
Supply Protection	Reverse voltage protection on Vs pin - prevents damage from battery polarity reversal during service

Pinout & Package

Package: PG-SSO-3-92 - surface-mount, 3-pin, leadless, thermally enhanced module with integrated 4.7 nF (Q–GND) and 47 nF (Vs–GND) ceramic capacitors for EMC compliance and micro-cut immunity.

Pin/Terminal	Circuit Role	Design Meaning
Vs	Positive supply input	Accepts 4.5–5.5 V; includes reverse-polarity protection diode
GND	Ground reference	Common return for analog/digital circuitry and integrated capacitor connections
Q	PWM output signal	Open-drain compatible, 3.3 V logic-level PWM with defined rise/fall times (typ. 100 ns)

Key Features

Feature	Design Value
Differential GMR Sensing	Two matched GMR bridge pairs enable rejection of common-mode field disturbances and axial misalignment
Adaptive Hysteresis	Self-adjusting threshold algorithm maintains switching accuracy across airgap variations and vibration-induced field noise
Integrated EMC Capacitors	On-module 4.7 nF (Q–GND) and 47 nF (Vs–GND) reduce PCB footprint and ensure repeatable EMI performance
Fast Startup	Valid direction-encoded PWM output within 3 magnetic edges (~100 µs typical) after power-on
Low Quiescent Current	Typ. 4.5 mA at 5 V - minimizes load on vehicle battery during idle and start-stop cycles

Applications

Automotive Crankshaft Sensing

Transmission Input Speed Sensing

Use Scenario: Detecting rotational speed and direction of crankshaft via ferromagnetic trigger wheel mounted on engine front end.

IC Role / Device Role / Timing Role: Differential GMR sensor providing edge-aligned PWM pulses synchronized to tooth/gap transitions for ECU ignition timing and misfire detection.

Use Value: 3.5 mm airgap capability allows flexible mounting behind timing cover; adaptive hysteresis eliminates false triggers during engine vibration.

Use Scenario: Monitoring input shaft rotation in automatic transmission using gear wheel with back-bias ferrite magnet.

IC Role / Device Role / Timing Role: Direction-sensitive speed transducer feeding torque converter lock-up control and shift strategy logic in TCU.

Use Value: Asymmetric CW/CCW pulse widths enable real-time direction validation without external logic; ±8 kV ESD withstands under-hood assembly environments.

Industrial Gearmotor Feedback

Hydraulic Pump Speed Monitoring

Use Scenario: Closed-loop speed control of high-torque industrial gearmotor driving conveyor systems.

IC Role / Device Role / Timing Role: Robust magnetic speed sensor interfacing directly to PLC input modules via PWM-compatible optocouplers.

Use Value: -40°C to +175°C operation supports uncooled gearbox housings; reverse-voltage protection prevents field-service damage during wiring.

Use Scenario: Real-time RPM monitoring of hydraulic pump shaft in off-highway equipment exposed to dust, oil, and shock.

IC Role / Device Role / Timing Role: High-jitter-performance GMR sensor delivering stable edge timing despite mechanical run-out and bearing wear.

Use Value: Integrated 47 nF Vs–GND capacitor suppresses supply ripple from solenoid switching; low 4.5 mA current draw extends battery backup runtime.

Equivalent & Alternatives

The following parts are listed as comparable options for similar differential speed and direction sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE5027C-I E6747	Swapped PWM timing: 90 µs CW / 45 µs CCW	Required where clockwise rotation must produce longer pulse for legacy ECU firmware compatibility	Select only if host controller expects inverted direction encoding logic
TLV4961-1KU	Single-GMR Hall hybrid; fixed 50% duty cycle PWM; no adaptive hysteresis	Limited to smaller airgaps (<1.2 mm); no direction resolution under zero-speed conditions	Use where cost sensitivity outweighs airgap flexibility and directional startup requirement

Compared with TLE5027CE6747HAMA1, the TLE5027C-I offers reversed PWM polarity for firmware-matching, while TLV4961-1KU sacrifices airgap margin and adaptive jitter suppression for lower BOM cost - making the original optimal for demanding powertrain edge detection with direction-critical timing.

FAQ

What is the function of the integrated 47 nF capacitor between Vs and GND?

This capacitor stabilizes the internal supply rail against fast transients induced by nearby solenoids or relay switching. It is factory-mounted and calibrated to work with the sensor's internal regulation, eliminating need for external bulk capacitance and ensuring consistent EMC performance per CISPR 25 Class 5 requirements.

Can TLE5027CE6747HAMA1 operate without a back-bias magnet in encoder wheel applications?

Yes - when used with a diametrically magnetized magnetic encoder wheel (N-S alternating poles), no external back-bias magnet is required. The GMR elements sense in-plane field components directly from the rotating pole structure, enabling compact, magnet-free designs in space-constrained modules.

How does the "hidden adaptive hysteresis" improve performance over fixed-threshold sensors?

It continuously monitors signal amplitude and noise floor during operation, then adjusts switching thresholds in real time to maintain clean edge detection during airgap variation, mechanical run-out, or thermal drift - reducing missed or double-counted edges without requiring recalibration or external tuning components.

Is the PG-SSO-3-92 package RoHS-compliant and lead-free?

Yes - the PG-SSO-3-92 package uses lead-free solder terminations and complies with EU RoHS Directive 2011/65/EU and REACH SVHC regulations. Full material declarations and test reports are available through Infineon's Product Change Notification system upon request.
