Product details
Overview
TLE49632MXTMA1 from Infineon Technologies is a bipolar Hall effect latch IC designed for high-precision position sensing in automotive powertrain and chassis systems. It operates from 3.0 V to 5.5 V, delivers ±5 mT magnetic operate/release thresholds with <0.28 µs jitter, and is qualified to AEC-Q100 Grade 0 (–40°C to +170°C) for engine bay and transmission applications.
For engineers reviewing the TLE49632MXTMA1 datasheet, TLE49632MXTMA1 pinout, TLE49632MXTMA1 application, or TLE49632MXTMA1 equivalent, this device supports robust commutation in brushless DC motors, index counting with pole wheels, and safety-critical window lifter and power closing systems requiring stable magnetic switching under extreme thermal stress.
Technical Context
The TLE49632MXTMA1 integrates a spinning Hall probe with chopper-stabilized amplifier, demodulator, low-pass filter, and comparator with hysteresis - enabling precise latch behavior with minimal offset drift over temperature. Its internal voltage regulator allows direct connection to a regulated 3.0–5.5 V rail, eliminating need for external LDO.
It features active error compensation circuitry that corrects for mechanical stress-induced offset and thermal hysteresis, ensuring repeatable BOP/BRP thresholds across its full –40°C to +170°C operating range. The open-drain output supports standard pull-up configurations compatible with 3.3 V or 5 V logic interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 5.5 V - supports direct interface with automotive-regulated rails without external regulation. |
| Operating Temperature | –40°C to +170°C - qualified per AEC-Q100 Grade 0 for under-hood and transmission-mounting locations. |
| Magnetic Thresholds | BOP = +5 mT, BRP = –5 mT - tight ±0.2 mT tolerance enables reliable pole-wheel index detection at high rotational speeds. |
| Jitter | Typ. 0.28 µs - ensures deterministic timing for motor commutation and safety-critical position feedback. |
| Output Type | Open-drain - allows flexible logic-level translation and wired-OR configuration with other sensors. |
| ESD Robustness | ±4 kV HBM - meets automotive system-level ESD immunity requirements without additional protection circuitry. |
| Supply Current | 1.5 mA - enables low-power operation in always-on vehicle subsystems such as body control modules. |
Pinout & Package
Package: PG-SOT23-3-15 - surface-mount, thermally enhanced plastic package with exposed die pad for improved heat dissipation in high-temperature environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Positive supply input | Accepts regulated 3.0–5.5 V; internal regulator supplies bias to all analog blocks. |
| 2 (Q) | Digital output terminal | Open-drain output; sinks current when latched; requires external pull-up for logic-high state. |
| 3 (GND) | Ground reference | Primary return path for supply and output current; connects to exposed die pad for thermal conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Spinning Hall probe architecture | Eliminates static offset drift and enables stable magnetic threshold performance over lifetime and temperature. |
| Chopper-stabilized amplifier | Reduces 1/f noise and input offset voltage, improving signal-to-noise ratio for weak-field detection. |
| Active error compensation | Corrects for packaging-induced stress and thermal hysteresis, maintaining ±0.2 mT BOP/BRP repeatability. |
| Integrated voltage regulator | Enables single-supply operation from noisy automotive rails without external LDO or filtering components. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bipolar Hall latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV4963-2K | Same magnetic thresholds (±5 mT), but rated only to +150°C; lower ESD rating (2 kV HBM). | Not qualified for Grade 0; unsuitable for transmission or turbocharger-mounted use cases. | Select only where ambient temperature remains below 150°C and ESD environment is controlled. |
| US5881LUA | Wider supply range (2.7–24 V); higher BOP/BRP (±10 mT); no AEC-Q100 qualification. | Lacks automotive qualification and thermal stability; intended for industrial appliances, not safety-critical systems. | Use only in non-automotive, cost-sensitive designs where extended voltage range outweighs precision and qualification needs. |
Compared with TLV4963-2K and US5881LUA, the TLE49632MXTMA1 uniquely combines Grade 0 temperature rating, ±5 mT precision, and AEC-Q100 qualification - making it the only choice for engine bay BLDC commutation and transmission feedback where thermal margin and functional safety are mandatory.

FAQ
What is the maximum allowable supply voltage for TLE49632MXTMA1?
The absolute maximum supply voltage is 6.0 V, but continuous operation must remain within 3.0 V to 5.5 V per specification. Exceeding 5.5 V risks permanent damage to the internal voltage regulator and Hall front-end circuitry, and violates AEC-Q100 stress test conditions.
Does TLE49632MXTMA1 require an external pull-up resistor on the Q pin?
Yes - the Q pin is open-drain and 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; values below 2.2 kΩ increase supply current without improving timing.
Can TLE49632MXTMA1 operate without a regulated supply?
No - the device requires a pre-regulated 3.0–5.5 V supply. Its internal regulator is not designed to handle unregulated battery transients (e.g., load dump up to 40 V); external LDO or DC-DC regulation is mandatory for direct battery connection.
Is the PG-SOT23-3-15 package RoHS and REACH compliant?
Yes - the PG-SOT23-3-15 package used for TLE49632MXTMA1 complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including exemption 7a for lead in high-melting-temperature solder alloys within the die attach material.
