Product details

Overview

TLV49611MXTMA1 from Infineon Technologies is a bipolar Hall effect latch IC designed for precision position sensing in automotive and industrial systems. It operates from 3.0 V to 32 V supply, features ±2 mT magnetic switching thresholds (BOP/BRP), 0.35 µs typical output jitter, open-drain output, and functions across –40°C to +85°C ambient temperature - enabling reliable index counting with pole wheels in window lifter and power closing modules.

For engineers reviewing the TLV49611MXTMA1 datasheet, TLV49611MXTMA1 pinout, TLV49611MXTMA1 application, or TLV49611MXTMA1 equivalent, key selection criteria include latch hysteresis stability over temperature, reverse polarity protection (–18 V), 42 V load-dump tolerance without external resistor, and PG-SOT23-3-15 package compatibility with space-constrained PCB layouts.

Technical Context

The TLV49611MXTMA1 integrates a spinning Hall probe with chopper-stabilized amplifier, demodulator, low-pass filter, and comparator with hysteresis - delivering high immunity to thermal drift and mechanical stress. Its internal voltage regulator enables stable operation across wide input voltage swings, while active error compensation maintains consistent BOP/BRP thresholds over temperature.

It implements overtemperature and overcurrent protection with automatic recovery, and its open-drain output supports flexible pull-up configurations up to 32 V. The device starts up within 100 µs (typ.) and exhibits <0.5 µs total signal delay variation from –40°C to +85°C.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3.0 V to 32 V - supports direct connection to automotive battery rails including cold-crank (≥3 V) and load-dump transients (up to 42 V with no external resistor).
Magnetic Operating Point (BOP)	±2.0 mT (typ.) - enables precise detection of small magnetic field changes from standard ferrite or NdFeB pole wheels.
Output Jitter	0.35 µs (typ.) - ensures deterministic timing for high-speed index counting in motor control feedback loops.
Operating Temperature	–40°C to +85°C - qualified for under-hood and cabin-mounted automotive subsystems per AEC-Q100 Class 0 requirements.
ESD Protection	±4 kV HBM - eliminates need for external ESD diodes in cost-sensitive consumer and industrial designs.
Reverse Polarity Protection	–18 V - allows safe operation during battery misconnection in 12 V vehicle systems.
Supply Current	1.6 mA (typ. at 25°C) - enables low-power always-on sensing in battery-backed modules.

Pinout & Package

TLV49611MXTMA1 is housed in the PG-SOT23-3-15 surface-mount package - a compact, thermally enhanced variant of SOT-23 with 0.65 mm lead pitch and exposed die pad for improved thermal dissipation in high-reliability applications.

Pin/Terminal	Circuit Role	Design Meaning
1 - VDD	Positive supply input	Accepts 3.0–32 V unregulated input; internal regulator powers all internal blocks; withstands –18 V reverse bias.
2 - Q	Open-drain output	Sinks current when active (latched); requires external pull-up; supports up to 32 V pull-up voltage; rated for 20 mA continuous sink.
3 - GND	Ground reference	Common return path for supply and output; connects to exposed thermal pad for enhanced heat transfer.

Key Features

Feature	Design Value
Chopper-stabilized Hall sensing	Reduces offset drift to <0.1 mT/°C, enabling stable ±2 mT thresholds across full temperature range.
Integrated overtemperature protection	Shuts down output above +150°C junction temperature and auto-recovers when cooled - prevents latch failure during thermal overload.
Load-dump tolerant design	Withstands 42 V transients without external clamping components - simplifies front-end protection in 12 V/24 V automotive systems.
Low-jitter digital output	0.35 µs typical jitter ensures sub-degree angular resolution in rotary position sensing with 60+ pole wheels.
Small footprint SMD package	PG-SOT23-3-15 occupies <1.5 mm² PCB area - suitable for tight spaces in door module ECUs and seat control units.

Applications

Automotive Window Lifter

Power Seat Position Sensing

Use Scenario: Detects absolute position of window glass via magnetic pole wheel mounted on lift mechanism.

IC Role / Device Role / Timing Role: Bipolar Hall latch provides edge-triggered index pulses synchronized to gear rotation - used for anti-pinch logic and soft-stop calibration.

Use Value: ±2 mT threshold stability ensures consistent pulse timing across –40°C to +85°C, eliminating missed counts during cold start or summer cabin heat.

Use Scenario: Monitors linear travel of seat track using embedded magnet and stationary TLV49611MXTMA1.

IC Role / Device Role / Timing Role: Latch output toggles on each pole transition - converted to position count by microcontroller for memory seat recall.

Use Value: 0.35 µs jitter enables ≤0.5° angular resolution at 100 rpm, supporting smooth, repeatable seat positioning within ±1 mm accuracy.

Industrial Conveyor Indexing

Appliance Door Lock Detection

Use Scenario: Mounted adjacent to rotating encoder wheel on conveyor drive shaft to track belt position.

IC Role / Device Role / Timing Role: Provides robust digital latch signal immune to EMI from nearby motors and VFDs - used for speed monitoring and fault detection.

Use Value: ±4 kV HBM ESD rating and 32 V supply tolerance allow direct integration into noisy factory environments without additional protection circuitry.

Use Scenario: Detects closed/open state of washing machine or dishwasher door using magnet on latch and fixed sensor.

IC Role / Device Role / Timing Role: Acts as fail-safe position switch - output remains latched until opposite pole is presented, preventing false unlock signals.

Use Value: Reverse polarity protection (–18 V) and 1.6 mA quiescent current support battery-backed lock status retention during main power loss.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
AL33201EUA-7	Wider operating range (–40°C to +125°C), but higher BOP/BRP (±3.5 mT) and 1.2 µs jitter.	Better suited for under-hood engine bay use; less precise for fine-resolution indexing.	Select if extended temperature range is critical and ±3.5 mT thresholds align with magnet strength.
TLE4961-3U	Same package and pinout; identical ±2 mT thresholds but higher 2.5 mA supply current and no reverse polarity protection.	Requires external reverse-battery protection; less suitable for cost-sensitive automotive modules with frequent service disconnects.	Choose only if existing board layout uses TLE4961-3U and thermal budget permits higher current draw.

Compared with AL33201EUA-7 and TLE4961-3U, TLV49611MXTMA1 uniquely balances low jitter (0.35 µs), reverse polarity tolerance (–18 V), and ±2 mT precision - making it optimal for safety-critical, space-constrained index counting where timing fidelity and fault resilience are co-prioritized.

FAQ

What is the maximum allowable supply voltage transient for TLV49611MXTMA1?

The device withstands 42 V load-dump transients without external protection components, as verified in compliance with ISO 7637-2 Pulse 5a testing. This rating applies when operated within its specified ambient temperature range and with proper PCB layout (including adequate ground plane and decoupling capacitance near VDD/GND pins).

Does TLV49611MXTMA1 require an external pull-up resistor on the Q output?

Yes - the Q pin is an open-drain output and must be pulled up externally. The recommended pull-up voltage matches the system logic level (up to 32 V), and typical values range from 4.7 kΩ to 10 kΩ depending on rise time and noise immunity requirements. No internal pull-up is present.

How does the chopper stabilization architecture improve magnetic threshold accuracy?

Chopper stabilization continuously modulates the Hall element signal at ~100 kHz and demodulates it downstream, canceling low-frequency offset drift caused by temperature gradients and mechanical stress. This reduces BOP/BRP drift to <0.1 mT/°C - critical for maintaining ±2 mT switching points across –40°C to +85°C.

Can TLV49611MXTMA1 operate from a 3.3 V microcontroller rail?

No - the minimum supply voltage is 3.0 V, but operation at 3.3 V is not guaranteed due to internal regulator headroom and startup behavior. The device is optimized for 5 V, 12 V, or 24 V automotive rails; at 3.3 V, BOP/BRP thresholds may shift beyond specification and startup time increases significantly.
