Product details

Overview

TLE49613MXTMA1 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, features ±7.5 mT magnetic switching thresholds (BOP/BRP), 0.35 µs typical output jitter, open-drain output, and AEC-Q100 qualified operation from −40°C to +170°C - enabling robust index counting with pole wheels in window lifters and power closing systems.

For engineers reviewing the TLE49613MXTMA1 datasheet, TLE49613MXTMA1 pinout, TLE49613MXTMA1 application, or TLE49613MXTMA1 equivalent, key selection criteria include magnetic threshold stability over temperature, load-dump tolerance up to 42 V without external components, reverse polarity protection (−18 V), integrated overcurrent/overtemperature protection, and PG-SOT23-3-15 package compatibility with space-constrained automotive PCB layouts.

Technical Context

The TLE49613MXTMA1 integrates a spinning Hall probe with chopper-stabilized amplifier, demodulator, low-pass filter, and comparator with hysteresis to deliver precise latching behavior under varying thermal and electromagnetic conditions. Its internal voltage regulator enables stable operation across wide input voltage swings, including automotive load-dump transients.

Functional block includes bias and compensation circuits, oscillator-driven sequencer, and active error compensation that maintains BOP/BRP drift ≤ ±0.15 mT over −40°C to +170°C. The open-drain output supports flexible pull-up configurations and interfaces directly with 3.3 V or 5 V microcontrollers without level-shifting.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3.0 V to 32 V - supports direct connection to unregulated automotive battery rails, including cold-crank (3 V) and load-dump (42 V transient)
Magnetic Operating Point (BOP)	+7.5 mT (typ.) - precise north-pole activation threshold for reliable pole-wheel edge detection
Magnetic Release Point (BRP)	−7.5 mT (typ.) - symmetric south-pole release threshold ensures clean latching hysteresis of 15 mT
Output Jitter	0.35 µs (typ.) - enables sub-degree angular resolution in motor commutation and speed sensing
Operating Temperature	−40°C to +170°C - qualified per AEC-Q100 Grade 0 for under-hood and transmission-mounted applications
ESD Protection	±4 kV HBM - eliminates need for external TVS diodes in most automotive harness environments
Reverse Polarity Protection	−18 V - withstands battery misconnection events without damage or latch-up

Pinout & Package

Delivered in PG-SOT23-3-15 - a lead-free, RoHS-compliant surface-mount package with 1.45 mm × 0.65 mm footprint, optimized for automated placement and thermal reliability in high-vibration environments.

Pin/Terminal	Circuit Role	Design Meaning
1 - VDD	Positive supply input	Accepts 3.0–32 V DC; internal regulator supplies all internal blocks; tolerates 42 V transients without external clamping
2 - Q	Open-drain output	Sinks current when active (latched); requires external pull-up; compatible with 3.3 V/5 V logic; supports wired-OR configurations
3 - GND	Ground reference	Low-impedance return path for supply and output; must be connected to system ground plane for EMC compliance

Key Features

Feature	Design Value
Active error compensation	Maintains ±0.15 mT BOP/BRP drift over full temperature range - eliminates recalibration in thermal cycling environments
Integrated overcurrent & overtemperature protection	Auto-recovery shutdown prevents latch failure during short-circuit or ambient overheating - no external fault-handling circuitry required
High ESD performance	±4 kV HBM rating - meets ISO 10605 requirements for automotive modules without added protection components
Small SMD package	PG-SOT23-3-15 footprint (1.45 mm × 0.65 mm) - enables placement near rotating targets with minimal air gap impact on field sensitivity
Load-dump tolerant design	Withstands 42 V transients per ISO 7637-2 Pulse 5a without external resistor - reduces BOM count and PCB area in battery-connected nodes

Applications

Power Window Lift Control

Seat Position Sensing

Use Scenario: Detects gear tooth or magnet pole transitions during powered window ascent/descent to prevent pinch detection false triggers and enable soft-stop control.

IC Role / Device Role / Timing Role: Bipolar latch provides deterministic edge-aligned digital output synchronized to mechanical rotation; hysteresis rejects vibration-induced chatter.

Use Value: ±7.5 mT thresholds ensure consistent switching across temperature and aging; 170°C rating allows placement near door motor housing.

Use Scenario: Mounted on seat track to monitor absolute position via multi-pole magnet array for memory seat recall and occupant classification.

IC Role / Device Role / Timing Role: Latch output toggles per magnet pole pair; jitter < 0.35 µs enables accurate velocity estimation for smooth actuator control.

Use Value: Reverse polarity protection (−18 V) safeguards against service disconnect errors; 32 V max supply accommodates 24 V commercial vehicle systems.

Transmission Gear Selector

Engine Crankshaft Position

Use Scenario: Integrated into gear lever assembly to detect discrete detent positions using embedded magnets for automatic transmission mode feedback.

IC Role / Device Role / Timing Role: Provides fail-safe digital state indication; open-drain output interfaces directly with ASIL-B microcontroller GPIO pins.

Use Value: AEC-Q100 Grade 0 qualification ensures reliability at 170°C under-hood; low supply current (1.6 mA) minimizes thermal loading in sealed assemblies.

Use Scenario: Mounted adjacent to crankshaft reluctor wheel to generate timing pulses for ignition and fuel injection synchronization.

IC Role / Device Role / Timing Role: Latching behavior captures first valid edge after engine start; internal regulator stabilizes output despite battery voltage sag during cranking.

Use Value: 42 V load-dump tolerance eliminates need for external TVS; ±0.15 mT BOP drift ensures consistent timing accuracy across engine thermal cycles.

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-002-REEL	Wider BOP/BRP spread (±10 mT), higher supply current (3.5 mA), no load-dump tolerance beyond 28 V	Lacks AEC-Q100 Grade 0 rating; max operating temperature +150°C limits under-hood use	Select when cost sensitivity outweighs thermal margin and transient robustness requirements
Allegro A1220LUA-T	Lower BOP/BRP (±3.5 mT), no reverse polarity protection, 5 V only supply	Requires external voltage regulation and reverse-protection circuitry; unsuitable for direct battery connection	Choose only for low-voltage, non-automotive industrial encoders where field strength is tightly controlled

Compared with US1881EUA-ABA-002-REEL and A1220LUA-T, TLE49613MXTMA1 delivers superior thermal stability, integrated protection, and direct battery-rail operation - reducing system-level BOM count and validation effort in automotive-grade motion sensing.

FAQ

What is the maximum allowable supply voltage transient for TLE49613MXTMA1?

The device withstands 42 V load-dump transients per ISO 7637-2 Pulse 5a without external components, verified in the official datasheet Revision 1.2 (2019-12-20), Section 3.2 Absolute Maximum Ratings. This rating applies to single-event transients up to 400 ms duration and does not imply continuous operation above 32 V.

Does TLE49613MXTMA1 require an external pull-up resistor on the Q output?

Yes - the Q pin is an open-drain output and requires an external pull-up resistor to a logic-compatible voltage (e.g., 3.3 V or 5 V). Datasheet Figure 7 and Figure 8 show both configurations: with and without external resistor, but pull-up is mandatory for defined high-state logic level and noise immunity.

How does the TLE49613MXTMA1 handle reverse battery connection?

It incorporates integrated reverse polarity protection rated to −18 V, meaning it remains undamaged and functional when VDD is connected to battery negative for durations specified in AEC-Q100 stress testing. No external diode or protection circuit is needed, as confirmed in Section 1.2 Features and Table 3 Absolute Maximum Ratings.

Is the magnetic hysteresis value fixed or temperature-dependent?

Hysteresis (BHys = BOP − BRP) is 15 mT nominal at 25°C and varies by ≤ ±0.3 mT over −40°C to +170°C, as shown in Figure 18 of the datasheet. This tight stability is achieved via active error compensation and is critical for consistent switching in thermally dynamic applications like transmission sensors.
