Product details
Overview
TLE49632MXTSA1 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 supports continuous operation from –40°C to +170°C in a PG-SOT23-3-15 package. Used in BLDC motor commutation and window lifter index counting.
For engineers reviewing the TLE49632MXTSA1 datasheet, TLE49632MXTSA1 pinout, TLE49632MXTSA1 application, or TLE49632MXTSA1 equivalent, this page provides verified magnetic thresholds, latch timing behavior, open-drain output drive capability, AEC-Q100 qualification status, and SOT23-3 pin mapping for direct integration into high-temp automotive signal chains.
Technical Context
The TLE49632MXTSA1 integrates a spinning Hall probe with chopper stabilization, on-chip voltage regulation, and comparator hysteresis to achieve stable magnetic switching across extreme temperature gradients. Its latch output retains state until opposite-polarity field reversal, eliminating need for external latching logic.
It uses active error compensation to suppress offset drift and achieves ±0.2 mT threshold variation over temperature (–40°C to 170°C). The open-drain output supports pull-up to 5.5 V and interfaces directly with 3.3 V or 5 V microcontrollers without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 5.5 V - compatible with regulated 3.3 V or 5 V automotive rails without external regulators. |
| Operating Temperature | –40°C to +170°C - qualified for under-hood and transmission-mounted applications. |
| Magnetic BOP / BRP | +5.0 mT / –5.0 mT - precise, symmetric latch thresholds enable reliable pole-wheel edge detection. |
| Output Type | Open-drain - allows wired-OR configuration and flexible pull-up voltage selection up to 5.5 V. |
| Jitter | Typ. 0.28 µs - ensures deterministic timing for high-speed rotor position sampling in BLDC motors. |
| ESD Robustness | ±4 kV HBM - meets automotive system-level ESD immunity requirements without added protection circuitry. |
| Supply Current | 1.5 mA - enables low-power operation in always-on vehicle modules. |
Pinout & Package
PG-SOT23-3-15: 3-pin surface-mount plastic package with gull-wing leads, 1.45 mm × 0.65 mm body, 0.95 mm height, and center-aligned Hall sensing area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Positive supply input | Accepts 3.0–5.5 V regulated rail; internal regulator supplies bias to analog blocks. |
| 2 (Q) | Open-drain output | Sinks current when active; requires external pull-up; logic-low = south pole detected. |
| 3 (GND) | Ground reference | Analog and digital ground return; must be low-impedance path to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Spinning Hall probe with chopper stabilization | Reduces thermal drift and 1/f noise, enabling ±0.2 mT threshold stability over full temperature range. |
| Active error compensation | Corrects for process variation and packaging stress, ensuring consistent BOP/BRP matching across production lots. |
| Integrated voltage regulator | Allows direct connection to noisy automotive 5 V rails while maintaining clean internal bias for analog circuitry. |
| High ESD immunity (HBM ±4 kV) | Eliminates need for external TVS diodes in most body-control module designs. |
Applications
| BLDC Motor Commutation | Power Window Index Counting |
|---|---|
Use Scenario: Detecting rotor magnet polarity transitions in 3-phase brushless DC motors for electronic control units. IC Role / Device Role / Timing Role: Bipolar latch providing synchronized, jitter-controlled edge signals to MCU timer capture inputs.

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 | BOP/BRP ±3.5 mT; max operating temp +150°C; no integrated regulator - requires clean 3.3 V supply. | Limited to lower-temperature cabin modules; less robust against supply ripple. | Select when cost sensitivity outweighs under-hood temperature margin and supply regulation needs. |
| Allegro A1220LUA-T | BOP/BRP ±5.5 mT; jitter 0.5 µs; operates to +150°C; no chopper stabilization - higher offset drift. | Higher timing uncertainty limits use in >15,000 RPM BLDC; reduced thermal stability affects long-term calibration. | Prefer where moderate jitter and wider thresholds are acceptable, and AEC-Q100 compliance is not mandatory. |
Compared with US1881EUA-ABA-000-RE and A1220LUA-T, the TLE49632MXTSA1 offers superior thermal stability (±0.2 mT vs. ±1.0+ mT drift), lower jitter (0.28 µs vs. ≥0.5 µs), and integrated regulation - making it the only choice for AEC-Q100-compliant, high-RPM, high-temperature automotive position sensing.

FAQ
What is the magnetic field polarity convention for TLE49632MXTSA1 output activation?
The TLE49632MXTSA1 output (Q) goes low when a south pole is presented to the marked face of the package (top side, center of sensitive area). North pole exposure releases the latch and returns Q to high-impedance state. This polarity definition is fixed and documented in Figure 8 of the datasheet.
Does TLE49632MXTSA1 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 a valid logic voltage (≤5.5 V). Typical values range from 2.2 kΩ to 10 kΩ depending on rise time and bus capacitance; no internal pull-up is provided.
Can TLE49632MXTSA1 operate directly from an unregulated 12 V automotive battery rail?
No - it requires a regulated supply between 3.0 V and 5.5 V. The internal regulator accepts only up to 5.5 V input; connecting directly to 12 V will damage the device. A pre-regulator (e.g., LDO or DC-DC converter) is mandatory.
Is TLE49632MXTSA1 pin-compatible with earlier TLE4961 or TLE4962 variants?
No - although functionally similar, TLE49632MXTSA1 uses PG-SOT23-3-15, whereas TLE4961/62 use PG-SSO-3 or other footprints. Pinout (VDD-Q-GND) matches electrically but mechanical layout and thermal pad design differ; PCB redesign is required for replacement.
