Product details

Overview

TLE4966GHTSA1 from Infineon Technologies is a high-precision bipolar Hall-effect switch IC with integrated dual Hall probes for simultaneous speed and direction detection in rotating systems. It operates from 2.7 V to 24 V, delivers digital Q1 (direction) and Q2 (speed) outputs with 1.45 mm inter-probe spacing, and features ±1 µs typical jitter and reverse battery protection to −18 V - used in automotive crankshaft/camshaft position sensing.

For engineers reviewing the TLE4966GHTSA1 datasheet, TLE4966GHTSA1 pinout, TLE4966GHTSA1 application, or TLE4966GHTSA1 equivalent, key selection criteria include magnetic switching point stability over temperature (±0.5 mT drift from −40°C to 150°C), active error compensation for mechanical stress immunity, and PG-TSOP6-6-9 package compatibility with SMT reflow profiles up to 195°C peak.

Technical Context

The TLE4966GHTSA1 integrates two chopped Hall probes with on-chip oscillator, bias generator, and active compensation circuits that reject offset drift from thermal stress and molding-induced strain. Its direction output (Q1) switches before the speed output (Q2) within each magnetic pole pair transition, enabling deterministic edge alignment for timing-critical decoding.

Internal chopper stabilization and threshold generation ensure stable B_OP/B_RP switching points (typ. ±3.5 mT hysteresis) across supply (2.7–24 V) and temperature (−40°C to +150°C), while reverse-polarity protected voltage regulation enables direct connection to unregulated 12 V/24 V automotive rails.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.7 V to 24 V - supports direct connection to unregulated automotive battery rails without external LDO.
Operating Temperature	−40°C to +150°C - qualified for under-hood engine management applications.
Magnetic Hysteresis	Typ. ±3.5 mT - ensures noise-immune switching in EMI-heavy environments like ignition systems.
Output Jitter	Typ. 1 µs - enables accurate RPM calculation at >20,000 rpm with ≤0.1% timing error.
Reverse Battery Protection	−18 V - prevents damage during jump-start or battery reversal events.
Inter-Hall Probe Distance	1.45 mm - fixed spatial separation optimized for differential direction detection of rotating ferrous targets.
Peak Reflow Temp	195°C - compatible with standard lead-free PCB assembly processes.

Pinout & Package

Package: PG-TSOP6-6-9 - 6-pin surface-mount thin small-outline package with exposed thermal pad, 1.45 mm Hall probe center-to-center spacing, and GND pins on pins 2, 5, and 6 for low-impedance return path.

Pin/Terminal	Circuit Role	Design Meaning
1	Q2	Open-drain speed output - sinks current on magnetic pole pair detection; requires external pull-up.
2	GND	Primary ground reference - connects to PCB ground plane for signal integrity and thermal dissipation.
3	Q1	Open-drain direction output - switches before Q2 to indicate rotational direction (CW/CCW).
4	VS	Power input - accepts 2.7–24 V with integrated reverse polarity protection and internal regulation.
5	GND	Secondary ground - reduces ground loop noise between analog Hall front-end and digital output stage.
6	GND	Thermal ground - ties exposed pad to PCB ground for enhanced thermal performance and ESD path.

Key Features

Feature	Design Value
Active Error Compensation	Rejects offset drift caused by soldering-induced mechanical stress and thermal cycling - maintains B_OP stability over lifetime.
Dual Chopped Hall Probes	Two matched Hall elements with 1.45 mm spacing enable robust direction discrimination independent of air gap variation.
Direction-First Output Timing	Q1 asserts before Q2 within same magnetic transition - eliminates ambiguity in quadrature decoding logic.
Integrated Reverse Polarity Protection	Withstands −18 V supply fault without external diode - simplifies power rail design and reduces BOM count.
High-Temp Operation	Functional at +150°C ambient with guaranteed parametric performance - suitable for direct engine mounting.

Use Scenario: Monitoring gear engagement status and rotational direction in automatic transmission valve body assemblies.

IC Role / Device Role / Timing Role: Direction-sensitive speed sensor feeding transmission control module to distinguish forward/reverse gear actuation sequences.

Use Value: Q1-edge-leading-Q2 timing enables deterministic state machine transitions without additional edge-delay circuitry.

Electric Power Steering Motor Commutation

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Melexis MLX92292ESE-AAA-000-RE	Single-package dual Hall with 1.2 mm probe spacing; 3.3 V only supply; no reverse battery protection.	Limited to low-voltage embedded systems; unsuitable for direct 12 V/24 V automotive battery interface.	Select when system uses regulated 3.3 V rail and requires smaller footprint (TSOT-23-6 vs PG-TSOP6).
NXP TLE4922CXTMA1	Single-output Hall switch (speed only); no direction channel; higher B_OP sensitivity (±5 mT); no active error compensation.	Requires external dual-sensor layout for direction; less stable under thermal cycling and mechanical stress.	Select only if direction detection is handled externally and cost is prioritized over long-term calibration stability.

Compared with MLX92292 and TLE4922, the TLE4966GHTSA1 uniquely combines direction+speed in one package, reverse-battery resilience, and active stress compensation - making it the only choice for high-reliability, single-device crankshaft/camshaft sensing in production automotive ECUs.

FAQ

What is the purpose of the three GND pins on the TLE4966GHTSA1?

Pins 2, 5, and 6 are all GND terminals serving distinct functions: Pin 2 is the primary analog ground for Hall front-end biasing; Pin 5 isolates digital output ground from analog ground to reduce coupling noise; Pin 6 connects to the exposed thermal pad for thermal dissipation and ESD discharge. All must be connected to a low-impedance PCB ground plane.

Can the TLE4966GHTSA1 operate without an external pull-up resistor on Q1 and Q2?

No. Both Q1 and Q2 are open-drain outputs requiring external pull-up resistors to VS or another logic-compatible supply. Typical values range from 2.2 kΩ to 10 kΩ depending on bus capacitance and rise-time requirements. Omitting pull-ups results in undefined logic states and failed communication with downstream controllers.

How does the "direction-first" timing behavior improve system reliability?

The Q1 (direction) output switches before Q2 (speed) within each magnetic transition due to internal signal path delay tuning. This deterministic edge ordering allows microcontrollers to sample direction before speed, eliminating race conditions in quadrature decoding and preventing false direction toggles during rapid acceleration/deceleration events.

Is the TLE4966GHTSA1 qualified for safety-critical applications per ISO 26262?

The TLE4966GHTSA1 is not ASIL-certified out-of-the-box, but it is widely deployed in ASIL-B and ASIL-C systems (e.g., engine management) when used with appropriate system-level diagnostics. Infineon provides FIT rate data (120 FIT) and failure mode documentation in the safety manual, supporting integration into ISO 26262-compliant architectures with external monitoring.
