Product details
Overview
TLI49632MXTMA1 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 output jitter, and operates across –40°C to +125°C with 3.0–5.5 V supply voltage. Used in BLDC motor commutation and window lifter index counting.
For engineers reviewing the TLI49632MXTMA1 datasheet, TLI49632MXTMA1 pinout, TLI49632MXTMA1 application, or TLI49632MXTMA1 equivalent, key selection criteria include magnetic threshold stability over temperature, open-drain output drive capability, SOT23-3 package compatibility, and latch behavior for edge-triggered position detection.
Technical Context
The TLI49632MXTMA1 integrates a spinning Hall probe with chopper-stabilized amplifier, demodulator, low-pass filter, and comparator with hysteresis - enabling high immunity to thermal drift and mechanical stress. Its internal voltage regulator ensures stable biasing across 3.0–5.5 V input, while active error compensation maintains ±5 mT BOP/BRP symmetry over full temperature range.
It functions as a digital latch: output Q remains latched low after magnetic south pole exposure until a north pole resets it. Timing behavior includes 0.28 µs propagation jitter (typ.) and <10 µs response time, supporting reliable detection in rotating systems with pole wheels at up to 20 kHz edge rates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 5.5 V - supports direct connection to standard 5 V rail without external regulation. |
| Magnetic Operate Point (BOP) | ±5 mT (typ.) - enables precise, repeatable switching with small air gaps in index wheel applications. |
| Output Type | Open-drain - allows wired-OR configuration and flexible pull-up voltage selection (up to 20 V). |
| Jitter (Propagation Delay) | 0.28 µs (typ.) - ensures timing-critical commutation signals remain synchronized across temperature. |
| Operating Temperature | –40°C to +125°C - validated for industrial motor control and power closure systems. |
| ESD Robustness | 4 kV HBM - reduces need for external protection in board-level ESD environments. |
| Supply Current | 1.5 mA (typ.) - enables low-power operation in battery-backed or energy-sensitive modules. |
Pinout & Package
TLI49632MXTMA1 is housed in the PG-SOT23-3-15 surface-mount package - a 3-pin, lead-free, RoHS-compliant variant of SOT-23 with standardized footprint and tape-and-reel packaging (3000 pcs/reel). The sensitive Hall element is centered beneath the package die pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Positive supply input | Accepts 3.0–5.5 V regulated DC; internal regulator powers all analog blocks. |
| 2 - Q | Digital output (open-drain) | Sinks current when active; requires external pull-up for logic-high level translation. |
| 3 - GND | Reference ground | Common return path for supply and output; must be low-impedance for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Active error compensation | Corrects offset drift in real time using chopper stabilization - eliminates need for external calibration. |
| High magnetic threshold stability | ±5 mT BOP/BRP maintained across –40°C to +125°C - enables single-threshold design in wide-temp systems. |
| Low propagation jitter | 0.28 µs (typ.) - supports accurate timing in high-speed BLDC rotor position sampling. |
| Integrated voltage regulator | Stabilizes internal bias rails from 3.0–5.5 V input - removes dependency on ultra-clean external LDO. |
| ESD protection | 4 kV HBM on all pins - meets IEC 61000-4-2 Level 3 for industrial equipment interfaces. |
Applications
| BLDC Motor Commutation | Automotive Power Window Lifters |

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 | Wider supply range (2.5–24 V), higher BOP/BRP (±10 mT), no integrated regulator | Supports unregulated 12 V automotive rails; less precise for fine-pole-wheel indexing | Choose when interfacing directly to 12 V systems without LDO; avoid where ±5 mT threshold accuracy is required. |
| Allegro A1120ELHLT-T | Lower temp range (–40°C to +85°C), no active error compensation, 1.8 µs jitter | Limited to consumer-grade appliances; unsuitable for industrial motor control above 85°C | Use only in cost-sensitive, non-automotive applications with ambient temperature <85°C and relaxed timing requirements. |
Compared with US1881EUA-ABA-000-RE and A1120ELHLT-T, TLI49632MXTMA1 provides superior thermal stability of magnetic thresholds and lower jitter - critical for high-accuracy commutation and index counting in extended temperature environments.

FAQ
Does TLI49632MXTMA1 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 to define the logic-high voltage level. A 4.7 kΩ resistor to 3.3 V or 5 V is typical. No internal pull-up is present, and leaving Q floating will result in undefined logic states during inactive periods.
Can TLI49632MXTMA1 operate from an unregulated 12 V supply?
No - its absolute maximum supply voltage is 5.5 V, and it requires a regulated 3.0–5.5 V input. Direct connection to 12 V will damage the device. A step-down regulator or LDO must be used upstream to meet the specified supply range.
What is the center location of the Hall sensing element in the PG-SOT23-3-15 package?
The sensitive area is centered 1.45 mm from the left edge (pin 1 side) and 0.65 mm from the top edge (marking side) of the package body, as defined in Figure 2 and Figure 9 of the datasheet. This location is critical for mechanical alignment with rotating magnets.
Is TLI49632MXTMA1 qualified for automotive AEC-Q100?
No - the datasheet explicitly states it is intended for industrial and consumer applications, not automotive. For AEC-Q100 qualified alternatives, Infineon's TLE496x series (e.g., TLE4963-2M) should be selected instead.
