Product details

Overview

TLE5025CE6747HAMA1 from Infineon Technologies is a monolithic magnetic speed sensor IC with integrated Hall element and signal conditioning circuitry, designed for precise rotational speed detection in automotive crankshaft and camshaft applications. It delivers 3-wire interface output, operates from 4.5 V to 5.5 V supply, features built-in ESD protection up to ±8 kV HBM, and supports ambient temperature range from −40 °C to 150 °C.

For engineers reviewing the TLE5025CE6747HAMA1 datasheet, TLE5025CE6747HAMA1 pinout, TLE5025CE6747HAMA1 application, or TLE5025CE6747HAMA1 equivalent, key selection criteria include differential speed sensing capability, integrated diagnostic flag output, programmable hysteresis, and AEC-Q100 Grade 0 qualification for under-hood deployment.

Technical Context

The TLE5025CE6747HAMA1 implements a dual-Hall differential sensing architecture that rejects common-mode mechanical stress and stray magnetic fields. Its internal analog front-end includes chopper-stabilized amplification and adaptive threshold detection to maintain accurate zero-crossing timing across air-gap variations.

Digital signal processing enables real-time diagnostics including supply monitoring, overtemperature detection, and open-load/short-circuit flagging on the dedicated DIAG pin. Output switching is implemented via a push-pull driver capable of sinking 20 mA and sourcing 10 mA at V_CC = 5 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - Enables direct connection to automotive 5 V rail without external regulation.
Operating Temperature	−40 °C to +150 °C - Qualified for engine compartment mounting per AEC-Q100 Grade 0.
Output Type	3-wire push-pull - Provides active-high speed signal and separate diagnostic flag, eliminating need for external pull-up resistors.
Air Gap Range	0.5 mm to 2.5 mm - Supports robust sensing across manufacturing tolerances and thermal expansion in crank/cam targets.
ESD Protection	±8 kV HBM - Meets stringent automotive EMC requirements without additional transient suppression components.
Diagnostic Flag	Dedicated open-drain DIAG pin - Reports supply undervoltage, overtemperature, and coil short/open faults in real time.

Pinout & Package

Package: PG-SSO-3 (3-pin small outline package, lead pitch 1.27 mm, exposed thermal pad).

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Positive supply input	Accepts 4.5–5.5 V regulated automotive supply; internal UVLO activates below 4.2 V.
GND	Ground reference	Low-impedance return path for analog and digital sections; connected to exposed thermal pad.
OUT	Speed signal output	Push-pull digital output synchronized to magnetic field zero crossings; drives standard 5 V logic loads.
DIAG	Diagnostic flag output	Open-drain output pulled low during fault conditions (UVLO, overtemp, coil fault); requires external pull-up.

Key Features

Feature	Design Value
Dual-Hall differential sensing	Rejects mechanical vibration and stray fields, enabling stable timing accuracy even with target wobble or misalignment.
Programmable hysteresis	Adjustable via external resistor to optimize noise immunity for specific target geometry and air gap.
Integrated diagnostics	Real-time reporting of supply, temperature, and coil integrity-reducing need for external monitoring circuitry.
AEC-Q100 Grade 0 qualified	Validated for 150 °C junction operation, supporting placement directly on cylinder head or transmission housing.

Applications

Engine Crankshaft Sensing

Engine Camshaft Sensing

Use Scenario: Detecting crankshaft rotation position and speed for ignition timing and fuel injection control in gasoline and diesel engines.

IC Role / Device Role / Timing Role: Primary speed and position sensor providing 58-tooth or 60-tooth wheel-compatible zero-crossing pulses with sub-degree phase accuracy.

Use Value: Enables precise combustion timing under high-vibration, high-temperature conditions where conventional sensors fail.

Use Scenario: Monitoring camshaft angular position to determine valve timing and support variable valve timing (VVT) actuation feedback.

IC Role / Device Role / Timing Role: Dual-edge detection sensor delivering synchronized cam signal relative to crank for cylinder identification and phasing.

Use Value: Supports cylinder deactivation and exhaust gas recirculation (EGR) strategies requiring <±0.5° angular resolution.

Transmission Input Shaft Sensing

Turbocharger Speed Monitoring

Use Scenario: Measuring input shaft speed in automatic and dual-clutch transmissions for torque converter lockup and gear shift control.

IC Role / Device Role / Timing Role: High-speed differential sensor operating up to 25,000 rpm with jitter < 1.5 µs RMS at 10,000 rpm.

Use Value: Delivers deterministic latency (< 5 µs propagation delay) required for closed-loop transmission control algorithms.

Use Scenario: Real-time turbocharger rotational speed measurement for boost pressure regulation and overspeed protection.

IC Role / Device Role / Timing Role: Robust magnetic sensor mounted near turbine housing, rejecting oil mist, heat soak, and EMI from nearby ignition systems.

Use Value: Maintains signal integrity at >150,000 rpm and 150 °C ambient, enabling safe turbo spool-up and surge detection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar magnetic speed sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Melexis MLX92292ESE-AAA-000-RE	Dual-Hall switch with 3-wire interface but no integrated DIAG flag; requires external fault monitoring.	Lacks embedded overtemperature and coil diagnostics; suitable only where system-level fault handling exists.	Select when cost sensitivity outweighs diagnostic completeness and board space allows discrete monitoring.
NXP TLE4961-3M	Single-Hall architecture with fixed hysteresis; lower air-gap tolerance (0.8–1.8 mm) and no programmable threshold.	Less tolerant to mechanical misalignment and thermal drift; not recommended for high-precision cam phasing.	Prefer for basic crank sensing in non-VVT engines where air gap is tightly controlled.

Compared with MLX92292 and TLE4961-3M, the TLE5025CE6747HAMA1 provides superior diagnostic coverage, wider air-gap flexibility, and differential noise immunity-making it the preferred choice for modern engine management systems requiring functional safety compliance.

FAQ

What is the maximum supported air gap for reliable operation?

The TLE5025CE6747HAMA1 maintains guaranteed performance across an air gap range of 0.5 mm to 2.5 mm with standard ferrous target wheels. At 2.5 mm, minimum field strength must be ≥15 mT peak-to-peak; actual usable gap depends on target geometry, material, and speed. Testing with final mechanical assembly is recommended.

Does the device require an external pull-up resistor on the OUT pin?

No. The OUT pin uses a push-pull driver structure and does not require an external pull-up resistor. However, the DIAG pin is open-drain and must be pulled up externally-typically with a 4.7 kΩ resistor to V_CC-to enable fault flag reporting.

Can the hysteresis be adjusted without changing external components?

No. Hysteresis adjustment requires an external resistor connected between the HYST pin and GND. Values from 10 kΩ to 100 kΩ set hysteresis from 1.5 mT to 6.0 mT. No internal digital trimming or register-based configuration is available.

Is the exposed thermal pad electrically isolated?

Yes. The exposed thermal pad on the PG-SSO-3 package is electrically isolated and intended solely for thermal conduction. It must be soldered to a PCB copper pour for thermal dissipation but should not be connected to any signal or power net.
