Product details

Overview

TLE49662GHTSA1 from Infineon Technologies is a high-precision dual Hall-effect speed sensor IC with two independent digital outputs (Q1, Q2), 2.7–24 V supply range, ±1.45 mm Hall plate spacing, and 1 μs typical jitter. It delivers phase-differentiated speed signals for rotational position sensing in automotive crankshaft and camshaft applications.

For engineers reviewing the TLE49662GHTSA1 datasheet, TLE49662GHTSA1 pinout, TLE49662GHTSA1 application, or TLE49662GHTSA1 equivalent, key selection criteria include magnetic threshold matching (BOP1 = BOP2), reverse battery protection (−18 V), peak junction temperature rating (195 °C), and PG-TSOP6-6-9 package compatibility with SMD reflow assembly.

Technical Context

The device integrates two chopped Hall probes with active error compensation to reject mechanical stress-induced offsets and ensure stable switching thresholds across temperature (−40 °C to 150 °C). Each probe drives a dedicated open-drain output stage with hysteresis-comparator logic.

Its chopper-stabilized architecture eliminates DC offset drift while maintaining precise, matched BOP/BRP thresholds (±1.5 mT matching) and low jitter (1 μs typ.)-critical for accurate edge timing in engine speed and position decoding.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	2.7 V to 24 V - supports direct connection to unregulated automotive battery rails including cold-crank (6.5 V) and load-dump (26 V transient)
Operating Temperature	−40 °C to +150 °C - qualified for under-hood engine control module placement
Junction Temp Limit	195 °C peak - enables short-duration exposure during solder reflow or thermal transients without latch-up
Magnetic Threshold Match	BOP1 = BOP2, BRP1 = BRP2 - ensures identical switching points for phase-accurate dual-channel timing
Output Jitter	1 μs typical - enables reliable 20 kHz+ signal edge detection in high-RPM engine monitoring
Reverse Battery Protection	−18 V - prevents damage during battery polarity reversal in service environments
Hall Plate Spacing	1.45 mm - provides fixed spatial separation for deterministic phase shift when sensing rotating pole wheels

Pinout & Package

Package: PG-TSOP6-6-9 - thermally enhanced thin-shrink small-outline package with exposed die pad, optimized for automotive-grade SMT assembly and thermal dissipation in sealed modules.

Pin/Terminal	Circuit Role	Design Meaning
1	Q2	Open-drain speed output 2 - sinks current when south-pole field exceeds BOP2; requires external pull-up
2	GND	Primary ground reference - connects to PCB ground plane for noise immunity and thermal conduction
3	Q1	Open-drain speed output 1 - independently switches on magnetic field crossing at H1; phase-shifted relative to Q2
4	VDD	Power input with integrated reverse-polarity protection - accepts 2.7–24 V with internal clamp to −18 V
5	GND	Secondary ground terminal - reduces ground loop impedance and improves EMI rejection
6	GND	Third ground terminal - enhances thermal path to PCB and stabilizes substrate potential under high-current transients

Key Features

Feature	Design Value

Dual Chopped Hall Probes	Eliminates DC drift and ensures <±1.5 mT BOP/BRP matching between channels over full temperature range
Integrated Reverse Polarity Protection	Withstands −18 V supply fault without external diode, reducing BOM count and board space
Low-Jitter Timing Outputs	1 μs typical propagation delay variation enables sub-degree crank angle resolution in ICE control
Thermal Robustness	Rated for 195 °C peak junction temperature - compatible with lead-free reflow profiles and under-hood thermal stress

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-output Hall speed sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX92292ESE-AAA-000-RE	Single-package dual Hall IC with programmable sensitivity and I²C configuration; 3.3 V only supply	Requires external level-shifting for 12 V systems; lacks reverse battery protection	Preferred where configurability and diagnostics outweigh ruggedness requirements
TLE4964-2K	Same PG-TSOP6 package but lower temp grade (150 °C max junction), no 195 °C peak rating	Not qualified for extended high-temp reflow or under-hood hot-soak conditions	Cost-optimized alternative for non-critical under-dash applications

Compared with MLX92292ESE-AAA-000-RE and TLE4964-2K, TLE49662GHTSA1 uniquely combines 195 °C peak thermal capability, −18 V reverse protection, and factory-matched dual thresholds-making it the only choice for safety-critical engine management speed sensing where long-term reliability under thermal and electrical stress is mandatory.

FAQ

What is the purpose of the three GND pins on TLE49662GHTSA1?

The three GND pins (pins 2, 5, and 6) provide low-impedance return paths for analog sensing circuitry, digital output stages, and thermal conduction. This layout minimizes ground bounce, improves EMI immunity, and enhances heat dissipation through the exposed die pad in the PG-TSOP6-6-9 package-critical for stable operation in noisy automotive environments.

Can TLE49662GHTSA1 operate directly from a 12 V car battery without external regulation?

Yes. The device operates over 2.7 V to 24 V and includes internal reverse-polarity protection (−18 V) and transient tolerance up to 26 V for 5 minutes. It is designed for direct connection to unregulated automotive battery rails, including cold-crank (6.5 V) and load-dump conditions, without external regulators or protection diodes.

How does the 1.45 mm Hall plate spacing affect signal output?

The fixed 1.45 mm spacing between Hall elements H1 and H2 creates a deterministic time delay between Q1 and Q2 output edges when sensing a rotating magnetic target. This phase shift enables direction detection and fine angular resolution in crankshaft/camshaft applications without requiring complex external interpolation or additional sensors.

Is TLE49662GHTSA1 qualified for use in safety-critical engine control systems?

Yes. It meets AEC-Q100 Grade 0 qualification (−40 °C to +150 °C), supports 195 °C peak junction temperature, and includes built-in diagnostic features such as active error compensation and matched channel thresholds-enabling compliance with ASIL-B functional safety requirements when integrated into properly architected control systems.
