Product details
Overview
TLI49631MXTMA1 from Infineon Technologies is a bipolar Hall effect latch IC optimized for 5 V industrial sensing applications, featuring ±2 mT magnetic operate/release thresholds, open-drain output, and operation from −40°C to +125°C with 1.5 mA supply current.
For engineers reviewing the TLI49631MXTMA1 datasheet, TLI49631MXTMA1 pinout, TLI49631MXTMA1 application, or TLI49631MXTMA1 equivalent, key selection criteria include magnetic threshold stability over temperature, low jitter (0.28 µs typ.), ESD robustness (4 kV HBM), and SOT23-3 compatibility in space-constrained designs.
Technical Context
The device integrates a spinning Hall probe with chopper-stabilized amplifier, demodulator, low-pass filter, and comparator with hysteresis to achieve high magnetic threshold accuracy and temperature stability. Its internal voltage regulator enables direct connection to a regulated 3.0–5.5 V supply without external conditioning.
Functional behavior includes latch-mode output toggling on magnetic polarity reversal, with default start-up state defined by initial field exposure. The sensitive area center is precisely aligned within the PG-SOT23-3-15 package for consistent mechanical mounting in rotary position sensing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 5.5 V - supports direct interface with standard 5 V logic rails and LDO-regulated systems. |
| Operating Temperature | −40°C to +125°C - qualified for industrial motor control and power actuator environments. |
| Magnetic BOP / BRP | +2 mT / −2 mT - tight ±2 mT switching thresholds enable precise pole-wheel index detection. |
| Output Type | Open-drain - allows wired-OR configuration and flexible pull-up voltage selection up to 24 V. |
| Jitter | 0.28 µs (typ.) - ensures timing-critical commutation signals remain stable across temperature and supply variation. |
| ESD Rating | 4 kV HBM - provides robust handling during PCB assembly and field operation in noisy industrial settings. |
| Supply Current | 1.5 mA (typ.) - enables low-power continuous monitoring in battery-backed or energy-sensitive systems. |
Pinout & Package
TLI49631MXTMA1 is housed in the PG-SOT23-3-15 surface-mount package (3-pin, 1.45 mm × 0.65 mm footprint), with standardized pin spacing and thermal pad design compatible with automated reflow processes.
| 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 requiring external pull-up; sinks up to 20 mA for direct LED/relay drive. |
| 3 (GND) | Reference ground | Common return path for supply and signal; must be low-impedance to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Spinning Hall probe | Eliminates offset drift and improves long-term magnetic threshold stability vs. static Hall elements. |
| Chopper-stabilized amplifier | Reduces 1/f noise and thermal drift, enabling <0.5 mT threshold variation over full temperature range. |
| Active error compensation | Corrects for process variation and packaging stress effects, ensuring consistent BOP/BRP matching across production lots. |
| Low-jitter timing | 0.28 µs typical propagation delay variation supports reliable BLDC motor commutation at >30 krpm. |
Applications
| Power Window Lift Control | Brushless DC Motor Commutation |

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-T | Wider supply range (2.7–24 V); higher BOP/BRP (±3.5 mT); no chopper stabilization. | Supports unregulated 12 V/24 V systems but exhibits greater threshold drift above 85°C. | Select when interfacing directly to automotive battery rails or where wider air gaps require higher sensitivity. |
| US1881EUA-AM | Lower supply current (3.5 mA); fixed 5 V only; no ESD rating specified beyond 2 kV HBM. | Suitable for cost-sensitive consumer devices but not rated for extended industrial temperature cycling. | Prefer for battery-powered appliances where power budget dominates over long-term thermal stability. |
Compared with AL3320EUA-T and US1881EUA-AM, TLI49631MXTMA1 delivers superior magnetic threshold stability (±0.3 mT max deviation over temp), lower jitter, and guaranteed 4 kV HBM robustness-making it optimal for closed-loop industrial motion control where repeatability and field reliability are critical.

FAQ
What is the recommended pull-up resistor value for the open-drain Q output?
A 4.7 kΩ resistor to 5 V is recommended per the datasheet application circuit, yielding ~1 mA output sink current while maintaining fast rise time (<100 ns) and noise immunity. Values between 2.2 kΩ and 10 kΩ are acceptable depending on bus capacitance and required slew rate.
Does TLI49631MXTMA1 require an external capacitor on VDD?
No external bypass capacitor is required due to integrated regulation and filtering; however, a 100 nF ceramic capacitor placed within 2 mm of the VDD and GND pins is recommended to suppress high-frequency noise from shared PCB power planes.
Can this device operate reliably with a 3.3 V supply?
Yes - the 3.0–5.5 V supply range includes 3.3 V systems. At 3.3 V, BOP/BRP remains ±2 mT (with minor reduction in output voltage swing), and jitter increases to 0.35 µs max, still sufficient for most BLDC commutation below 20 krpm.
Is the PG-SOT23-3-15 package RoHS and REACH compliant?
Yes - the PG-SOT23-3-15 package meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin plating and halogen-free molding compound, as confirmed in Infineon's material declaration document 2019-12-20 rev. 1.2.
