Product details
Overview
TLI49611MXTMA1 from Infineon is a bipolar Hall effect latch IC designed for industrial position sensing and commutation. It operates from 3.0 V to 32 V, draws 1.6 mA typical supply current, features ±2 mT magnetic switching thresholds (BOP/BRP), open-drain output, and supports −40°C to +125°C ambient temperature - ideal for brushless DC motor rotor position detection and index counting with pole wheels.
For engineers reviewing the TLI49611MXTMA1 datasheet, TLI49611MXTMA1 pinout, TLI49611MXTMA1 application, or TLI49611MXTMA1 equivalent, key selection criteria include unregulated supply tolerance, reverse polarity protection (−18 V), overvoltage capability up to 42 V without external resistor, low jitter (0.35 μs typ.), and active error compensation for stable magnetic thresholds across temperature and stress.
Technical Context
The TLI49611MXTMA1 integrates a spinning Hall probe with chopper-stabilized amplifier, demodulator, low-pass filter, and comparator with hysteresis to deliver precise latching behavior. Its internal voltage regulator and bias generator enable operation across wide supply rails while maintaining threshold stability.
It implements active error compensation to reject offset drift from mechanical stress (e.g., molding/soldering) and thermal gradients. The output stage includes integrated overcurrent and overtemperature protection, and default power-on behavior forces Q high regardless of applied magnetic field until first BOP/BRP crossing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 32 V - supports direct connection to unregulated industrial rails (e.g., 24 V PLC bus) without external regulation. |
| Supply Current | 1.6 mA typical - enables low-power continuous operation in battery-backed or energy-constrained systems. |
| Magnetic Thresholds | BOP = +2 mT, BRP = −2 mT - symmetric bipolar latch behavior ensures reliable switching with standard pole wheels or magnets. |
| Output Type | Open-drain - allows flexible pull-up configuration and wired-OR interfacing with microcontrollers or logic inputs. |
| Operating Temperature | −40°C to +125°C - qualified for harsh industrial environments including motor control enclosures and factory automation cabinets. |
| Jitter | 0.35 μs typical - minimizes timing uncertainty in high-speed commutation (e.g., >30k RPM BLDC motors). |
| ESD Performance | High ESD robustness - eliminates need for external TVS diodes in many applications unless >4 kV HBM required. |
Pinout & Package
TLI49611MXTMA1 uses the PG-SOT23-3-15 package - a small, halogen-free SMD outline with gull-wing leads, optimized for automated assembly and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Supply voltage input | Accepts 3.0–32 V; includes reverse polarity protection (−18 V) and overvoltage tolerance (42 V). |
| 2 - Q | Open-drain output | Sinks up to 25 mA; requires external pull-up; compatible with 1.8 V to 32 V logic interfaces. |
| 3 - GND | Ground reference | Common return path for supply and output; must be low-impedance for stable magnetic threshold performance. |
Key Features
| Feature | Design Value |
|---|---|
| Chopper-stabilized architecture | Eliminates offset drift from packaging stress and temperature gradients, ensuring ±2 mT threshold stability over life. |
| Integrated protection | On-chip overcurrent and overtemperature shutdown prevents failure during fault conditions without external circuitry. |
| Wide supply range with no external components | Operates from 3.0 V to 32 V and withstands 42 V transients - removes need for external Zener or TVS in most industrial designs. |
| Low-jitter switching | 0.35 μs typical propagation delay variation - enables accurate timing in high-RPM motor commutation and encoder indexing. |
| Reverse polarity protection | Withstands −18 V supply reversal - protects against wiring errors in field-deployed equipment. |
Applications
| Brushless DC Motor Commutation | Pole-Wheel Index Counting |
|---|---|
|
Use Scenario: Detecting rotor magnet polarity in 3-phase BLDC motors for electronic commutation. IC Role / Device Role / Timing Role: Bipolar latch providing synchronized edge-triggered signals to MCU timer inputs for phase alignment. Use Value: Stable ±2 mT thresholds ensure consistent zero-crossing detection across temperature, enabling smooth torque delivery at speeds up to 30k RPM. |
Use Scenario: Counting gear teeth or slots on rotating shafts using ferrous pole wheels. IC Role / Device Role / Timing Role: Magnetic latch generating clean digital pulses per tooth passage for position feedback. Use Value: Low jitter (0.35 μs) preserves pulse edge integrity at high rotational speeds, reducing count error in CNC or packaging machinery. |
| Industrial Valve Position Sensing | Conveyor Belt Speed Monitoring |
|
Use Scenario: Monitoring linear or rotary actuator position in pneumatic/hydraulic valves. IC Role / Device Role / Timing Role: Latching sensor detecting magnet presence at end-of-travel positions. Use Value: −40°C to +125°C rating ensures reliability inside sealed valve manifolds exposed to ambient heat and process fluids. |
Use Scenario: Measuring belt speed via embedded magnets or ferrous markers on drive pulleys. IC Role / Device Role / Timing Role: Open-drain output interfaced to PLC high-speed counter inputs. Use Value: 32 V supply compatibility allows direct connection to 24 V industrial control buses 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 |
|---|---|---|---|
| TLI49611LXTMA1 | Same die, PG-SSO-3-2 package with different pinout (VDD-GND-Q vs. VDD-Q-GND) and leaded construction. | Preferred where leaded assembly or higher creepage is required; not drop-in compatible due to pin reordering. | Select when board layout accommodates SSO-3 footprint and leaded soldering is specified. |
| Melexis US1881EUA-ABA-000-REEL | ±3.5 mT thresholds, 3.5–24 V supply, no reverse polarity protection, 500 ns jitter. | Lacks overvoltage tolerance and reverse polarity protection; less suited for unregulated 24 V industrial rails. | Consider only if lower cost is critical and system-level protection is already implemented externally. |
Compared with TLI49611MXTMA1, the TLI49611LXTMA1 offers identical electrical performance in a leaded package but requires PCB redesign, while the US1881EUA provides lower cost at the expense of supply robustness and magnetic precision - making the TLI49611MXTMA1 optimal for demanding industrial motion control.

FAQ
What is the pin configuration of TLI49611MXTMA1?
TLI49611MXTMA1 uses the PG-SOT23-3-15 package with Pin 1 = VDD, Pin 2 = Q (open-drain output), and Pin 3 = GND. This differs from the TLI49611LXTMA1 (PG-SSO-3-2), which has Pin 1 = VDD, Pin 2 = GND, Pin 3 = Q. Layout files must match the correct footprint and pin mapping.
Does TLI49611MXTMA1 require an external pull-up resistor?
Yes - the Q output is open-drain and requires an external pull-up resistor to a valid logic voltage (1.8 V to 32 V). Typical values range from 1 kΩ to 10 kΩ depending on rise time and bus capacitance. No external current-limiting resistor is needed for supply protection due to built-in overvoltage tolerance up to 42 V.
Can TLI49611MXTMA1 be used in automotive applications?
No - TLI49611MXTMA1 is explicitly rated for industrial and consumer use only and is not AEC-Q100 qualified. Infineon recommends the TLE-series Hall switches (e.g., TLE4961-1K) for automotive applications, which include extended qualification, enhanced ESD, and broader temperature grading.
How does the active error compensation work in TLI49611MXTMA1?
Active error compensation uses a chopper-stabilized architecture that periodically reverses the Hall plate bias and signal path polarity. This cancels offset voltages caused by mechanical stress (e.g., from molding or thermal cycling) and process variations, ensuring ±2 mT magnetic thresholds remain stable across −40°C to +125°C and product lifetime.
