Product details
Overview
TLV49641MXTSA1 from Infineon Technologies is a unipolar Hall effect switch IC designed for precision position sensing in automotive and industrial systems. It operates from 3.0 V to 32 V supply, features open-drain output, BOP = 18 mT (typ), BRP = 12.5 mT (typ), and hysteresis = 5.5 mT - enabling robust detection of ferrous targets in noisy environments such as engine camshaft or gearbox position monitoring.
For engineers reviewing the TLV49641MXTSA1 datasheet, TLV49641MXTSA1 pinout, TLV49641MXTSA1 application, or TLV49641MXTSA1 equivalent, key selection criteria include magnetic threshold stability over temperature (±0.1 mT/°C), low jitter (0.35 µs typ), reverse polarity protection (–18 V), overvoltage tolerance (42 V without external resistor), and integrated overcurrent/overtemperature protection.
Technical Context
The TLV49641MXTSA1 integrates a spinning Hall probe with chopper-stabilized amplification and demodulation to suppress offset drift and 1/f noise. Its comparator includes built-in hysteresis (5.5 mT) and is referenced to a stable internal voltage regulator that maintains operation across 3.0–32 V input.
Functional block includes oscillator-driven sequencing, bias and compensation circuits for thermal drift correction, and active error compensation logic that dynamically adjusts thresholds to maintain consistent switching points from –40°C to +85°C - critical for engine bay and industrial motor control deployments.
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 load-dump transients up to 42 V without external clamping. |
| Operating Point (BOP) | 18 mT (typ) - precise magnetic field threshold for turn-on; enables reliable detection of small ferrous targets at air gaps up to 2.5 mm. |
| Release Point (BRP) | 12.5 mT (typ) - ensures clean signal release with 5.5 mT hysteresis, preventing chatter near threshold in vibration-prone environments. |
| Output Type | Open-drain N-channel - allows flexible pull-up to any voltage ≤32 V and simplifies interfacing with microcontrollers or PLC inputs. |
| Supply Current | 1.6 mA (typ at 25°C) - enables low-power operation in always-on vehicle subsystems like door latch or seat position monitoring. |
| Jitter | 0.35 µs (typ) - guarantees timing-critical edge detection for crankshaft/camshaft synchronization in ICE engine management. |
| ESD Protection | ±4 kV HBM - meets automotive-grade robustness requirements without additional external protection components. |
Pinout & Package
TLV49641MXTSA1 is housed in PG-SOT23-3-15 - a lead-free, RoHS-compliant surface-mount package with 1.45 mm × 1.3 mm footprint, 0.95 mm height, and exposed thermal pad for enhanced thermal dissipation in high-ambient applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Positive supply input | Accepts 3.0–32 V DC; internal regulator powers all analog blocks; reverse polarity protection down to –18 V prevents damage during battery misconnection. |
| 2 - Q | Open-drain output | Sinks current when active; requires external pull-up; compatible with 3.3 V or 5 V logic; output current limited to 20 mA (typ) with thermal foldback. |
| 3 - GND | Ground reference | Common return path for supply and output; must be connected directly to PCB ground plane to ensure EMC compliance and accurate magnetic sensing. |
Key Features
| Feature | Design Value |
|---|---|
| Spinning Hall sensor architecture | Eliminates offset drift and 1/f noise, enabling ±0.1 mT/°C magnetic threshold stability over full temperature range. |
| Integrated overtemperature protection | Shuts down output above 160°C junction temperature and auto-recovers when cooled - prevents latch-up in enclosed motor housings. |
| Active error compensation | Dynamically corrects for process variation and aging effects, maintaining BOP/BRP consistency across production lots and lifetime. |
| Load-dump tolerant design | Withstands 42 V transients per ISO 7637-2 Pulse 5a without external TVS or Zener - reduces BOM count in automotive body control modules. |
| Low-jitter timing response | 0.35 µs typical propagation delay variation ensures sub-degree crank angle resolution in engine timing applications. |
Applications

Use Value: High ESD rating (±4 kV HBM) withstands static discharge in humid laundry environments; hysteresis prevents false triggers from vibration-induced magnet oscillation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unipolar Hall switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE4964-1M | Same pinout and electrical specs; differs only in marking code and tape/reel packaging (PG-SOT23-3-15 vs. PG-SOT23-3-15 variant). | No functional difference; identical magnetic thresholds, jitter, and protection features. | Select based on distributor stock availability and reel size requirements (3000 pcs vs. 10000 pcs). |
| HAL1506SU | Higher BOP (25 mT), wider operating range (–40°C to +150°C), but no integrated overvoltage protection beyond 36 V. | Better suited for high-temp exhaust proximity sensing; lacks 42 V load-dump tolerance required in main battery rail applications. | Choose HAL1506SU only if ambient exceeds 85°C and external TVS is acceptable; otherwise TLV49641MXTSA1 provides superior system-level robustness. |
Compared with TLE4964-1M, TLV49641MXTSA1 offers identical performance with verified traceability to Infineon's SP000965280 ordering code; versus HAL1506SU, it trades higher temperature rating for guaranteed 42 V transient immunity and lower jitter - making it preferred for engine bay and BCM deployments where supply rail integrity is unpredictable.

FAQ
What is the maximum allowable supply voltage transient for TLV49641MXTSA1?
The device withstands 42 V load-dump transients per ISO 7637-2 Pulse 5a without external protection components. This rating applies only when no external series resistor is used in the VDD path. Exceeding 42 V or applying sustained overvoltage beyond absolute maximum ratings (45 V) may cause permanent damage.
Does TLV49641MXTSA1 require an external pull-up resistor on the Q pin?
Yes - the Q pin is an open-drain N-channel output and requires an external pull-up resistor to a logic-compatible voltage (≤32 V). Typical values range from 2.2 kΩ to 10 kΩ depending on rise time and bus capacitance; no internal pull-up is provided.
How does the active error compensation feature improve long-term reliability?
Active error compensation continuously monitors and corrects for Hall element offset drift caused by temperature gradients, mechanical stress, and aging. This maintains BOP and BRP within ±0.3 mT over 15 years of operation - eliminating field failures due to magnetic threshold shift in safety-critical position sensing.
Can TLV49641MXTSA1 operate with a 3.3 V microcontroller interface?
Yes - the open-drain Q output can be pulled up to 3.3 V, and the device functions correctly down to 3.0 V supply. However, VDD must remain ≥3.0 V; the IC does not regulate or level-shift - it simply sinks current when activated, making it fully compatible with 3.3 V logic inputs.
