Product details
Overview
TLV49611MXTSA1 from Infineon Technologies is a bipolar Hall effect latch IC designed for precise position and speed sensing in automotive and industrial systems. It operates from 3.0 V to 32 V supply, features ±2 mT magnetic switching thresholds (BOP/BRP), 0.35 µs typical output jitter, open-drain output, and functions reliably from −40°C to +85°C - enabling robust index counting with pole wheels in window lifters and power-closing mechanisms.
For engineers reviewing the TLV49611MXTSA1 datasheet, TLV49611MXTSA1 pinout, TLV49611MXTSA1 application, or TLV49611MXTSA1 equivalent, key selection criteria include magnetic threshold stability over temperature, reverse polarity protection (−18 V), load-dump tolerance up to 42 V without external resistor, integrated overcurrent/overtemperature protection, and PG-SOT23-3-15 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV49611MXTSA1 implements a spinning Hall probe with chopper-stabilized amplifier and demodulator to suppress offset drift and enhance magnetic threshold accuracy. Its comparator includes hysteresis (typ. 4 mT) and is driven by a low-noise, temperature-compensated reference derived from an internal voltage regulator and bias circuitry.
Functional sequencing is managed by an oscillator and state machine that controls power-on timing (tPON ≤ 100 µs), output signal delay (<1.5 µs), and error compensation during transient conditions - ensuring deterministic switching behavior under varying supply and thermal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 32 V - supports direct connection to automotive battery rails including cold-crank (≥3 V) and load-dump transients (up to 42 V without external resistor). |
| Magnetic Operating Point (BOP) | +2.0 mT (typ.) - precise north-pole activation threshold enabling accurate edge detection in rotating pole-wheel systems. |
| Magnetic Release Point (BRP) | −2.0 mT (typ.) - symmetric south-pole release point ensures clean latching behavior with 4 mT hysteresis for noise immunity. |
| Output Type | Open-drain N-channel MOSFET - allows flexible pull-up to any voltage ≤32 V and supports wired-OR configurations. |
| Supply Current | 1.6 mA (typ. at 25°C, 5 V) - enables low-power operation in always-on vehicle modules without excessive thermal load. |
| Output Jitter | 0.35 µs (typ.) - minimizes timing uncertainty in high-speed index counting applications such as motor commutation feedback. |
| ESD Protection | ±4 kV HBM - eliminates need for external ESD protection in typical automotive harness environments. |
Pinout & Package
TLV49611MXTSA1 is housed in the PG-SOT23-3-15 surface-mount package - a compact, lead-free, RoHS-compliant 3-pin variant of SOT-23 with gull-wing leads and defined die centering for consistent magnetic field sensitivity alignment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Positive supply input | Accepts 3.0–32 V DC; includes reverse polarity protection (−18 V) and internal regulation for stable core biasing. |
| 2 - Q | Open-drain output | Sinks current when active; requires external pull-up; supports voltage levels independent of VDD (e.g., 5 V or 12 V logic interface). |
| 3 - GND | Ground reference | Common return path for supply and output current; must be low-impedance to maintain magnetic threshold stability. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage capability | Withstands 42 V transients without external resistor - simplifies design for 12 V/24 V automotive systems exposed to load-dump events. |
| Active error compensation | Real-time correction of Hall plate offset and thermal drift - maintains ±2 mT BOP/BRP stability across −40°C to +85°C. |
| Low-jitter output | 0.35 µs typical timing uncertainty - enables reliable pulse counting at rotational speeds exceeding 10,000 RPM in window lifter motors. |
| Integrated protection | On-chip overcurrent and overtemperature shutdown - prevents latch failure during short-circuit or ambient overheating conditions. |
| Reverse polarity protection | Withstands −18 V applied to VDD - eliminates risk of damage during battery terminal misconnection in service environments. |
Applications
| Automotive Window Lifter | Power-Closing Actuator |
|---|---|

IC Role / Device Role / Timing Role: High-stability latch delivering deterministic on/off transitions despite vibration, EMI, and wide ambient temperature swings. Use Value: 4 mT hysteresis and chopper stabilization suppress false triggering from mechanical bounce or electromagnetic noise in factory-floor environments. |
Use Scenario: Providing rotor position feedback for BLDC motor control in washing machine drum drives and HVAC blowers. IC Role / Device Role / Timing Role: Open-drain output interfacing directly with 3.3 V or 5 V MCU GPIO pins while tolerating 24 V system rail fluctuations. Use Value: Integrated overcurrent protection prevents latch damage during motor phase short circuits - eliminating need for discrete current-limiting components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bipolar Hall latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV49612MXTSA1 | Same package and pinout; BOP/BRP shifted to +3.5 mT / −3.5 mT - higher magnetic sensitivity threshold. | Better suited for larger air gaps or weaker magnets; less tolerant of stray fields in dense sensor arrays. | Select when magnet strength varies significantly or when reduced susceptibility to EMI is required. |
| HAL1506UTA | PG-SSO-3 package; 2.7–24 V supply; ±3.0 mT thresholds; no integrated overvoltage protection beyond 28 V. | Lacks 42 V load-dump tolerance and reverse polarity protection - requires external TVS and diode. | Choose only if footprint compatibility with SSO-3 is mandatory and system-level protection is already implemented. |
Compared with TLV49612MXTSA1 and HAL1506UTA, TLV49611MXTSA1 delivers superior magnetic threshold stability over temperature, broader supply resilience, and fully integrated protection - making it optimal for cost-sensitive, high-reliability automotive body electronics where board space and BOM count are constrained.

FAQ
What is the maximum allowable supply voltage transient for TLV49611MXTSA1?
The device withstands 42 V transients without external components, per its overvoltage capability specification. This rating applies to load-dump events defined in ISO 7637-2 Pulse 5a, and is validated across the full operating temperature range. No external Zener or TVS diode is required for compliance in standard 12 V automotive systems.
Can TLV49611MXTSA1 operate with a 3.3 V microcontroller I/O rail?
Yes - its open-drain output supports pull-up to any voltage ≤32 V, including 3.3 V logic. The output saturation voltage remains ≤0.4 V at 10 mA sink current, ensuring valid LOW-level recognition by 3.3 V CMOS inputs. No level-shifting circuitry is needed.
How does the chopper stabilization affect magnetic threshold drift?
Chopper stabilization actively cancels Hall plate offset drift caused by temperature gradients and process variation. As a result, BOP and BRP shift by only ±0.2 mT from −40°C to +85°C - a 10× improvement over non-chopped Hall latches - ensuring consistent switching points across vehicle lifetime.
Is the PG-SOT23-3-15 package compatible with standard SOT-23 reflow profiles?
Yes - the PG-SOT23-3-15 is JEDEC-standard compliant and qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1. It supports peak reflow temperatures up to 260°C and is compatible with standard lead-free solder profiles used for automotive-grade assemblies.
