Product details
Overview
TLI49611MXTSA1 from Infineon is a bipolar Hall effect latch IC designed for industrial position sensing and commutation, featuring ±2 mT magnetic switching thresholds (BOP/BRP), 3.0–32 V supply range, 1.6 mA quiescent current, open-drain output, and operation from −40°C to +125°C. It enables precise rotor position detection in BLDC motors and index counting with pole wheels.
For engineers reviewing the TLI49611MXTSA1 datasheet, TLI49611MXTSA1 pinout, TLI49611MXTSA1 application, or TLI49611MXTSA1 equivalent, key selection criteria include magnetic threshold stability, unregulated supply tolerance, reverse polarity protection (−18 V), overvoltage capability (42 V), and low jitter (0.35 μs) in harsh industrial environments.
Technical Context
The TLI49611MXTSA1 implements a spinning Hall probe with chopper-stabilized amplification and active error compensation to reject offset drift from thermal stress and packaging effects. Its comparator includes hysteresis (BHYS = 4 mT) and internal overtemperature/overcurrent protection on the open-drain output stage.
It operates as a latch: output remains latched high or low until the magnetic field crosses BOP (+2 mT) or BRP (−2 mT), with default power-on output set to high (VQ) regardless of initial field condition. The internal voltage regulator supports direct connection to unregulated rails up to 42 V without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 32 V - supports direct connection to unregulated industrial rails; withstands transient overvoltage up to 42 V. |
| Quiescent Current | 1.6 mA at 25°C - enables low-power operation in always-on industrial monitoring systems. |
| Magnetic Thresholds | BOP = +2 mT, BRP = −2 mT - symmetric bipolar latch behavior ideal for pole-wheel counting and BLDC rotor position sensing. |
| Output Type | Open-drain N-channel - allows flexible pull-up configuration and wired-OR interfacing with microcontrollers or logic inputs. |
| Operating Temperature | −40°C to +125°C - qualified for extended industrial ambient conditions without derating. |
| Jitter | Typ. 0.35 μs - ensures precise timing in high-speed commutation applications (e.g., >30k RPM BLDC). |
| ESD Performance | HBM ≥ 2 kV - robust against handling and board-level electrostatic discharge in manufacturing and field service. |
Pinout & Package
TLI49611MXTSA1 is packaged in PG-SOT23-3-15 - a halogen-free, leaded SMD package with 1.3 mm × 2.9 mm footprint and 1.45 mm height, optimized for automated assembly and thermal reliability in industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Supply input | Accepts 3.0–32 V DC; internally regulated to power analog and digital blocks; tolerates −18 V reverse polarity. |
| 2 - Q | Open-drain output | Sinks up to 25 mA; requires external pull-up; provides latched high/low state based on magnetic field crossing BOP/BRP. |
| 3 - GND | Ground reference | Common return path for supply and output; must be low-impedance to maintain magnetic threshold stability. |
Key Features
| Feature | Design Value |
|---|---|
| Chopper-stabilized Hall sensing | Eliminates offset drift from mechanical stress and temperature gradients, enabling ±0.1 mT threshold stability over life. |
| Integrated overtemperature protection | Shuts down output above safe junction temperature and auto-recovers when cooled - prevents latch failure during overload. |
| Reverse polarity protection | Withstands −18 V applied to VDD without damage - simplifies wiring in field-deployed equipment with potential polarity reversal. |
| Overvoltage capability | Operates up to 42 V without external resistor - removes need for Zener clamping in 24 V industrial systems. |
| Low-jitter switching | 0.35 μs typical propagation delay variation - ensures deterministic timing for real-time motor control loops. |
Applications
| BLDC Motor Commutation | Pole-Wheel Index Counting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bipolar Hall latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLI49611LXTSA1 | Same die, PG-SSO-3-2 package (2.08 × 1.35 mm); higher thermal resistance (RthJA = 220 K/W vs. 190 K/W); different pinout (GND on Pin 2, Q on Pin 3). | Preferred for space-constrained boards where SSO-3's smaller footprint offsets slightly lower thermal performance. | Select TLI49611LXTSA1 only if layout constraints favor PG-SSO-3-2 and thermal margin ≥15°C is available. |
| Melexis US1881EUA-ABA-000-REEL | Wider supply range (2.5–36 V); higher BOP/BRP (±3.5 mT); no reverse polarity protection; no overvoltage tolerance beyond 36 V. | Used in cost-sensitive consumer appliances but lacks industrial-grade fault protections and thermal stability. | Choose only for non-critical, low-voltage (<24 V), non-reverse-wiring applications where ±3.5 mT thresholds are acceptable. |
Compared with TLI49611MXTSA1, the TLI49611LXTSA1 offers identical electrical performance in a smaller package but reduced thermal headroom, while the US1881EUA lacks reverse polarity and overvoltage protection-critical for industrial field reliability.

FAQ
What is the default output state at power-on?
At power-on, TLI49611MXTSA1 forces its open-drain output (Q) to the high-impedance (pull-up) state regardless of the applied magnetic field. This behavior is guaranteed by internal start-up logic and ensures predictable initialization in motor control and counting systems before field stabilization.
Does this device require an external pull-up resistor?
Yes - the open-drain output requires an external pull-up resistor to VDD or another logic rail. Typical values range from 1 kΩ to 10 kΩ depending on rise time requirements and bus loading; 4.7 kΩ is recommended for 12 V systems with ≤100 ns rise time targets.
Can TLI49611MXTSA1 operate directly from a 24 V unregulated supply?
Yes - it operates continuously from 3.0 V to 32 V and survives transients up to 42 V without external protection. Its integrated voltage regulator and overvoltage-hardened front-end eliminate the need for Zener diodes or series resistors in standard 24 V industrial power domains.
Is this part qualified for automotive use?
No - TLI49611MXTSA1 is explicitly rated for industrial and consumer applications only. It is not AEC-Q100 qualified. For automotive-grade Hall latches, Infineon recommends the TLE496x series, which includes extended temperature screening, enhanced ESD, and automotive-specific qualification testing.
