Product details
Overview
TLI49632MXTSA1 from Infineon Technologies is a bipolar Hall effect latch IC designed for precision position sensing in 5 V regulated supply systems. It delivers ±5 mT magnetic operate/release thresholds, 0.28 µs typical jitter, and operates across –40°C to +125°C with open-drain output. Used in BLDC motor commutation and window lifter index counting where stable latching behavior under thermal stress is critical.
For engineers reviewing the TLI49632MXTSA1 datasheet, TLI49632MXTSA1 pinout, TLI49632MXTSA1 application, or TLI49632MXTSA1 equivalent, key selection criteria include magnetic threshold stability over temperature, low-jitter switching timing, open-drain drive capability into pull-up loads, and PG-SOT23-3-15 package compatibility with high-density PCB layouts.
Technical Context
The TLI49632MXTSA1 integrates a spinning Hall probe with chopper-stabilized amplifier, demodulator, and comparator with hysteresis to achieve high immunity to offset drift and thermal instability. Its internal voltage regulator enables operation from 3.0 V to 5.5 V while maintaining consistent magnetic thresholds.
It implements active error compensation and uses an oscillator-driven sequencer to control bias and signal path timing. The latch output remains stable until reverse polarity field exceeds BRP (–5 mT), ensuring robust state retention in rotating pole-wheel environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 5.5 V - supports direct connection to standard 5 V rails without external regulation. |
| Operating Temperature | –40°C to +125°C - qualified for industrial-grade thermal cycling in motor control enclosures. |
| BOP / BRP | +5 mT / –5 mT - symmetric, tightly matched thresholds enable precise zero-crossing detection on pole wheels. |
| Output Type | Open-drain - allows flexible pull-up to 5 V or 3.3 V, supports wired-OR configurations and level translation. |
| Jitter (typ.) | 0.28 µs - ensures sub-microsecond timing consistency for high-RPM commutation (e.g., >30,000 RPM BLDC). |
| ESD (HBM) | ±4 kV - provides robust handling margin during SMT assembly and field operation in noisy industrial settings. |
| Supply Current | 1.5 mA - enables low-power indexing in battery-backed or energy-constrained subsystems. |
Pinout & Package
TLI49632MXTSA1 is housed in the PG-SOT23-3-15 surface-mount package - a compact, lead-free, RoHS-compliant variant of SOT-23 with standardized footprint and tape-and-reel packaging for automated placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Positive supply input | Accepts 3.0–5.5 V regulated DC; internal regulator supplies bias to analog core and digital logic. |
| 2 (Q) | Open-drain output | Sinks current when active (B-field ≥ +5 mT); requires external pull-up for logic-high state. |
| 3 (GND) | Ground reference | Common return for supply and output; must be low-impedance to minimize noise coupling into Hall sensor. |
Key Features
| Feature | Design Value |
|---|---|
| Spinning Hall probe | Eliminates static offset drift, enabling <±0.2 mT threshold variation over full temperature range. |
| Chopper-stabilized amplifier | Reduces 1/f noise and thermal drift, preserving signal integrity at low field strengths. |
| Active error compensation | Dynamically corrects for process and temperature-induced mismatches in comparator hysteresis. |
| Low-jitter timing | 0.28 µs typical propagation delay variation ensures deterministic edge placement for timing-critical commutation. |
| High ESD robustness | 4 kV HBM rating reduces need for external protection components in motor-drive PCB layouts. |
Applications
| BLDC Motor Commutation | Automotive Window Lifter |
|---|---|
Use Scenario: Detecting rotor pole position in 3-phase brushless DC motors for electronic commutation. IC Role / Device Role / Timing Role: Bipolar latch providing synchronized digital edge transitions aligned to magnetic zero-crossings. Use Value: Enables precise 120° electrical phase alignment with ±0.5° mechanical angle tolerance at 30,000 RPM due to low jitter and stable BOP/BRP. |
Use Scenario: Counting gear teeth on a window lift mechanism to detect end-of-travel and prevent motor stall. IC Role / Device Role / Timing Role: Index latch generating one pulse per gear tooth passage using pole-wheel excitation. Use Value: Delivers reliable counting up to 100 mm/s linear speed with no missed pulses, thanks to symmetric ±5 mT thresholds and fast recovery time. |
| Industrial Power Closing System | Appliance Door Lock Sensor |
Use Scenario: Monitoring actuator position in automated industrial doors to verify full closure before locking sequence. IC Role / Device Role / Timing Role: Latched position indicator confirming presence of ferrous target within fixed air gap. Use Value: Maintains state integrity across thermal cycles (–40°C to +125°C), eliminating false triggers caused by threshold drift. |
Use Scenario: Sensing door closure status in washing machines and dishwashers via embedded magnet in latch assembly. IC Role / Device Role / Timing Role: Fail-safe proximity detector with open-drain output interfacing directly to microcontroller GPIO. Use Value: 1.5 mA supply current and 5 V compatibility simplify integration into existing 5 V appliance control boards without level-shifting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bipolar Hall latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL3320EUA-7 | Wider supply range (2.5–24 V), higher BOP/BRP (±10 mT), no chopper stabilization. | Less precise at low fields; suited for coarse position detection in high-voltage industrial actuators. | Select when operating above 5.5 V or needing extended air-gap tolerance; avoid for high-RPM commutation. |
| US1881EUA-7 | Lower supply current (3.5 mA), no active error compensation, ±3.5 mT thresholds, 1.5 µs jitter. | Higher timing uncertainty limits use to ≤5,000 RPM motors and non-critical indexing. | Choose for cost-sensitive consumer appliances where thermal stability and jitter are secondary to BOM cost. |
Compared with AL3320EUA-7 and US1881EUA-7, TLI49632MXTSA1 offers superior thermal stability and sub-microsecond jitter-critical for closed-loop motor control-while maintaining strict 5 V compatibility and minimal board space via PG-SOT23-3-15.

FAQ
Is TLI49632MXTSA1 qualified for automotive applications?
No. The TLI49632MXTSA1 is explicitly designated for industrial and consumer use only. Infineon does not qualify it to AEC-Q100 or automotive reliability standards. For automotive-grade alternatives, refer to the TLE series (e.g., TLE4963-2M), which undergo additional qualification testing and offer extended temperature screening.
What is the recommended pull-up resistor value for the open-drain Q output?
A 4.7 kΩ pull-up to 5 V is recommended per the datasheet application circuit (Figure 7). This value balances rise time (<1 µs), power dissipation (<1 mW static), and noise immunity. Values below 2.2 kΩ increase current draw unnecessarily; above 10 kΩ may degrade edge sharpness in noisy environments.
Can TLI49632MXTSA1 operate from an unregulated 5 V supply?
No. The device requires a regulated supply between 3.0 V and 5.5 V. Its internal voltage regulator is designed for stable biasing-not input ripple suppression. Unregulated 5 V sources with >100 mV peak-to-peak ripple may cause erratic switching or increased jitter, as confirmed in Section 2.1 and Figure 7 of the datasheet.
Does TLI49632MXTSA1 support bidirectional magnetic field detection in a single package?
Yes. As a bipolar latch, it responds to both North and South pole fields: it turns ON when exposed to ≥+5 mT (South pole facing sensitive area) and remains latched until exposed to ≤–5 mT (North pole), enabling true direction-agnostic position sensing without external polarity logic.
