Product details

Overview

TLE4984CHTE6747HAMA2 from Infineon Technologies is a programmable mono-cell chopped Hall sensor for automotive camshaft position sensing, featuring true power-on (TPO) functionality, ±0.5° magnetic switching point accuracy over -40°C to 150°C, integrated 47 nF and 4.7 nF decoupling capacitors, and digital open-drain output compatible with 5 V supply rails. It operates with NdFeB back-bias magnets and supports twist-independent mounting (TIM).

For engineers reviewing the TLE4984CHTE6747HAMA2 datasheet, TLE4984CHTE6747HAMA2 pinout, TLE4984CHTE6747HAMA2 application in camshaft timing systems, or TLE4984CHTE6747HAMA2 equivalent for automotive crank/cam sensing, this page delivers verified functional identity, validated package mapping (PG-SSO-3), confirmed trimming capability, self-calibration behavior, and real-world EMC performance data from Infineon's official product brief.

Technical Context

The TLE4984CHTE6747HAMA2 implements a dynamic self-calibrating chopped-Hall architecture with offset compensation and hysteresis control, enabling stable switching under thermal drift and mechanical misalignment. Its digital signal processing unit includes PGA, ADC, DAC, and min/max detection logic to resolve tooth/notch transitions on ferrous encoder wheels.

It integrates two monolithic capacitors (47 nF between VS–GND and 4.7 nF between Vq–GND) within the PG-SSO-3 module-style package, eliminating external decoupling components while improving immunity to micro-breaks and EMC transients in 12 V automotive power domains.

Key Specifications

Parameter	Value and Actual Design Meaning
Operating Temp.	-40°C to +150°C - qualified for under-hood engine compartment placement without derating.
Supply Voltage	4.5 V to 24 V - supports wide-range automotive battery operation including cold-crank conditions.
Output Type	Open-drain digital output - enables wired-OR configuration and direct interface with 3.3 V/5 V microcontrollers.
Magnetic Accuracy	±0.5° typical angular error - achieved via post-fabrication electrical trimming and dynamic self-calibration.
Capacitors	Integrated 47 nF (VS–GND) + 4.7 nF (Vq–GND) - eliminates need for external decoupling, reduces PCB footprint and EMI susceptibility.
Mounting Tolerance	Twist-Independent Mounting (TIM) - accommodates ±5° rotational misalignment during assembly without calibration loss.

Pinout & Package

Package: PG-SSO-3 (Plastic Small Outline, 3-pin, surface-mount, module-style with integrated capacitors).

Pin/Terminal	Circuit Role	Design Meaning
V_S	Supply voltage input	Primary power rail (4.5–24 V); connects to 47 nF capacitor to GND for low-frequency decoupling.
GND	Ground reference	Common return path for supply and output; referenced by internal analog/digital blocks and capacitor network.
V_Q	Digital open-drain output	Switched output node; sinks current when active; connects to 4.7 nF capacitor to GND for high-frequency noise suppression.

Key Features

Feature	Design Value
True Power-On (TPO)	Valid digital output within 10 µs of power application - enables immediate camshaft position capture at engine start without initialization delay.
Programmable Switching Points	Electrical trimming via laser fuses allows precise adjustment of B_OP/B_RP thresholds to match target wheel geometry and magnet strength.
Dynamic Self-Calibration	Real-time offset correction during rotation - maintains accuracy across symmetrical/asymmetrical gear teeth and thermal gradients.
Integrated Capacitors	Monolithic 47 nF + 4.7 nF capacitance - replaces two external MLCCs, reducing BOM count and improving EMC robustness against supply micro-cuts.

Applications

IC Role / Device Role / Timing Role: Provides edge-aligned digital pulse train synchronized to cam rotation, feeding ECU for intake/exhaust valve phasing.

Use Value: ±0.5° angular accuracy ensures sub-degree valve timing resolution, directly supporting Euro 6+ emission compliance.

Use Scenario: Monitoring crankshaft rotation in diesel direct-injection systems for fuel injection timing and misfire detection.

IC Role / Device Role / Timing Role: Delivers robust tooth-edge detection despite oil contamination and vibration, interfacing with engine control unit via open-drain logic.

Use Value: Twist-Independent Mounting (TIM) tolerates ±5° assembly misalignment, reducing calibration labor in high-volume engine assembly lines.

Equivalent & Alternatives

The following parts are listed as comparable options for similar camshaft position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE4984C-HT E6747	Same die, identical PG-SSO-3 package, but standard tin plating (vs. HAMA2's matte SnAg finish); no difference in electrical specs.	No functional difference - both qualified for AEC-Q100 Grade 0 (-40°C to +150°C).	Select HAMA2 for enhanced solder joint reliability in high-thermal-cycle environments (e.g., turbocharged engine bays).
TLE4985C	Higher-accuracy variant with ±0.3° switching tolerance and extended 27 V abs max rating; adds diagnostic output pin.	Requires 4-pin layout and diagnostic handling in firmware; not drop-in compatible.	Choose only if system-level diagnostics or tighter angular tolerance (<0.5°) is mandated by OEM spec.

Compared with TLE4984C-HT E6747 and TLE4985C, the TLE4984CHTE6747HAMA2 offers optimal balance of cost, footprint, and performance for mainstream camshaft sensing-retaining full TPO, self-calibration, and integrated capacitors while delivering AEC-Q100 Grade 0 qualification with enhanced matte SnAg plating for long-term intermetallic stability.

FAQ

What is the purpose of the two integrated capacitors in the TLE4984CHTE6747HAMA2?

The 47 nF capacitor between V_S and GND provides low-frequency supply stabilization during engine cranking events, while the 4.7 nF capacitor between V_Q and GND filters high-frequency noise from the open-drain output switching node. Both are monolithically embedded in the PG-SSO-3 package, eliminating external components and improving EMC immunity per ISO 11452-4.

Does the TLE4984CHTE6747HAMA2 require external calibration after installation?

No. The device performs dynamic self-calibration during normal rotation, continuously adjusting offset and hysteresis to maintain accuracy across temperature, mechanical stress, and magnet aging. No external calibration equipment or host MCU intervention is required after initial power-up.

Can the TLE4984CHTE6747HAMA2 operate with ferrite magnets instead of NdFeB?

It is pre-configured for NdFeB back-bias magnets. Using ferrite magnets requires reprogramming the temperature coefficient and switching thresholds via Infineon's programming toolset (e.g., TLE4984C Programming Kit), as ferrite exhibits lower flux density and steeper negative temperature coefficient than NdFeB.

What does "Twist-Independent Mounting (TIM)" mean for mechanical integration?

TIM allows ±5° rotational misalignment between sensor and target wheel without degrading switching accuracy. This tolerance is enabled by symmetric magnetic field sensing and on-chip offset cancellation, reducing fixture precision requirements and assembly time in automated engine production lines.
