Product details

Overview

TLE49614MXTSA1 from Infineon Technologies is a bipolar Hall effect latch IC designed for high-precision position sensing in automotive powertrain and body electronics. It operates from 3.0 V to 32 V supply, delivers ±10 mT magnetic switching thresholds (BOP/BRP), features open-drain output with 1.6 mA supply current, and supports -40°C to +170°C ambient temperature - enabling direct integration into motor-driven window lifters and seat adjusters.

For engineers reviewing the TLE49614MXTSA1 datasheet, TLE49614MXTSA1 pinout, TLE49614MXTSA1 application, or TLE49614MXTSA1 equivalent, key selection criteria include latch hysteresis stability over temperature, load-dump tolerance up to 42 V without external components, ESD robustness (±8 kV HBM), and PG-SOT23-3-15 package compatibility with automated SMT assembly.

Technical Context

The TLE49614MXTSA1 implements a spinning Hall plate architecture with chopper-stabilized amplification and demodulation to suppress offset drift and thermal hysteresis. Its comparator includes built-in hysteresis (typ. 20 mT) referenced to internal bandgap voltage, ensuring stable BOP/BRP across temperature.

Internal voltage regulation enables operation from unregulated automotive batteries, while integrated overtemperature and output overcurrent protection activate at 170°C junction and >100 mA sink current respectively. The device powers on in <100 μs and exhibits <0.35 μs output jitter - critical for accurate edge timing in index-pulse counting.

Key Specifications

ESD Robustness	±8 kV HBM - eliminates need for external TVS diodes in most automotive PCB layouts.

Pinout & Package

Delivered in PG-SOT23-3-15 - a lead-free, RoHS-compliant surface-mount package with 1.45 mm × 0.65 mm footprint and 0.95 mm max height, optimized for high-density automotive PCBs.

Pin/Terminal	Circuit Role	Design Meaning
1 - VDD	Positive supply input	Accepts 3.0–32 V DC; integrates reverse polarity protection (−18 V) and overvoltage clamp (42 V).
2 - Q	Open-drain output	Sinks up to 100 mA; requires external pull-up; logic-low = magnetic field present (south pole).
3 - GND	Ground reference	Common return path for supply and output; connects to substrate for thermal dissipation and EMC control.

Key Features

Feature	Design Value

High ESD immunity	±8 kV HBM - meets ISO 10605 requirements without external ESD suppression on Q or VDD lines.
Fast power-on response	tPON < 100 μs - ensures immediate readiness after ignition switch activation or wake-up events.

Applications

Power Window Lift Control

Seat Position Sensing

Use Scenario: Detecting gear tooth or pole wheel rotation during electric window motor actuation to prevent pinch detection timeout and enable soft-stop positioning.

IC Role / Device Role / Timing Role: Bipolar latch providing synchronized index pulses per revolution to MCU for real-time angular position tracking.

Use Value: ±10 mT thresholds ensure consistent switching across temperature and mechanical tolerances; 170°C rating allows placement near motor housing.

Use Scenario: Monitoring linear actuator position in power-adjustable driver seats using magnet-embedded slider rails.

IC Role / Device Role / Timing Role: Latching Hall sensor generating direction-aware quadrature-like signals via dual-device arrangement.

Use Value: Low 1.6 mA supply current extends battery backup runtime; open-drain output simplifies interface with 3.3 V MCU GPIO.

Transmission Gear Selector

Steering Column Angle Feedback

Use Scenario: Detecting detent positions in electronic shift-by-wire systems where mechanical linkage is replaced by hall-sensed cam profiles.

IC Role / Device Role / Timing Role: High-stability latch delivering deterministic ON/OFF transitions at defined magnetic angles for gear state validation.

Use Value: 20 mT hysteresis prevents chatter during slow-position transitions; AEC-Q100 qualification ensures functional safety compliance.

Use Scenario: Measuring absolute steering angle via multi-pole ring magnet coupled to column shaft in EPS systems.

IC Role / Device Role / Timing Role: Precision latch capturing magnetic polarity reversals to derive coarse angular sectors for redundancy with resolver or AS5x47 sensors.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bipolar Hall latch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Melexis US1881EUA-ABA-000-RE	Wider BOP/BRP spread (±15 mT), higher supply current (2.5 mA), no integrated overvoltage clamp beyond 28 V.	Limited to 150°C max ambient; requires external Zener for 42 V load-dump protection.	Preferred where cost sensitivity outweighs extended temperature or transient robustness needs.
Allegro A1220LUA-T	Lower hysteresis (12 mT), no chopper stabilization, 125°C max junction temperature, ±4 kV HBM ESD rating.	Not AEC-Q100 qualified; unsuitable for under-hood or transmission environments.	Applicable only in cabin-grade consumer or industrial non-automotive designs.

Compared with US1881EUA-ABA-000-RE and A1220LUA-T, the TLE49614MXTSA1 provides superior thermal stability, integrated 42 V transient handling, and full AEC-Q100 Grade 0 qualification - making it the only choice for safety-critical, high-temperature automotive position sensing.

FAQ

What is the maximum allowable supply voltage transient for TLE49614MXTSA1?

The device withstands 42 V load-dump transients per ISO 7637-2 without external clamping components. This rating applies to single-event pulses ≤400 ms duration with energy ≤100 J. Continuous operation above 32 V is not permitted, and repeated exposure to transients exceeding 42 V may degrade long-term reliability.

Does TLE49614MXTSA1 require an external pull-up resistor?

Yes - the open-drain Q output requires an external pull-up resistor to VDD or another logic rail. Typical values range from 2.2 kΩ to 10 kΩ depending on rise time and bus capacitance. Figure 7 in the datasheet shows a minimal application circuit using only this resistor; no additional passive components are needed for basic operation.

How does the chopper stabilization improve performance over conventional Hall latches?

Chopper stabilization actively cancels offset voltage drift caused by temperature gradients and process variation. In the TLE49614MXTSA1, this reduces magnetic threshold drift to <0.1 mT/°C - enabling ±10 mT BOP/BRP stability across −40°C to +170°C, whereas non-chopped devices typically drift >0.5 mT/°C and require calibration or compensation.

Can TLE49614MXTSA1 be used in bidirectional current sensing applications?

No - it is a dedicated bipolar Hall latch for position and proximity detection, not a linear Hall sensor. It outputs only digital ON/OFF states based on magnetic polarity and magnitude relative to fixed thresholds. For current sensing, Infineon's TLV4971 or XENSIV™ TLI4971 series provide ratiometric analog or digital current output with galvanic isolation.
