Product details
Overview
TLV49613MXTMA1 from Infineon Technologies is a bipolar Hall effect latch IC designed for precision position sensing in automotive and industrial systems. It operates from 3.0 V to 32 V supply, features ±7.5 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 power window lifters and seat actuators.
For engineers reviewing the TLV49613MXTMA1 datasheet, TLV49613MXTMA1 pinout, TLV49613MXTMA1 application, or TLV49613MXTMA1 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, and integrated overcurrent/overtemperature protection in PG-SOT23-3-15 package.
Technical Context
The TLV49613MXTMA1 uses a spinning Hall probe with chopper-stabilized amplifier and demodulator to suppress offset drift and achieve high magnetic threshold stability. Its comparator includes hysteresis (typ. 15 mT) and is driven by a low-pass filtered signal path optimized for clean edge detection under EMI stress.
Internal voltage regulation enables operation across wide supply ranges (3.0–32 V), while active error compensation and oscillator-controlled sequencing ensure consistent startup behavior and timing integrity. The device outputs a digital latch signal via open-drain topology compatible with 3.3 V or 5 V pull-up rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 32 V - supports direct connection to unregulated 12 V/24 V automotive rails including transient load-dump events up to 42 V without external protection. |
| Magnetic Operating Point (BOP) | ±7.5 mT (typ.) - precise latching threshold enables accurate zero-crossing detection with standard ferrous pole wheels. |
| Output Jitter | 0.35 µs (typ.) - ensures sub-microsecond timing consistency critical for high-speed index counting in motor control feedback loops. |
| Operating Temperature | −40°C to +85°C - qualified for under-hood and cabin-mounted automotive modules per AEC-Q100 Class 2 requirements. |
| ESD Protection | ±4 kV HBM - provides robust handling during PCB assembly and system integration without additional clamping circuitry. |
| Reverse Polarity Protection | −18 V - allows safe operation during battery misconnection in vehicle service environments. |
| Supply Current | 1.6 mA (typ. at 25°C) - enables low-power always-on sensing in energy-sensitive body electronics applications. |
Pinout & Package
TLV49613MXTMA1 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 thermal pad exposure for enhanced reliability in reflow-soldered automotive assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Positive supply input | Accepts 3.0–32 V DC; internal regulator derives bias for analog front-end and logic; tolerates −18 V reverse and 42 V transients. |
| 2 - Q | Open-drain output | Sinks current when active (latched); requires external pull-up; compatible with 3.3 V or 5 V logic families; supports wired-OR configurations. |
| 3 - GND | Ground reference | Common return for supply and output; connects to substrate thermal pad for improved thermal dissipation in high-ambient environments. |
Key Features
| Feature | Design Value |
|---|---|
| Chopper-stabilized Hall sensing | Reduces offset drift to <0.1 mT/°C, enabling stable BOP/BRP over full temperature range without calibration. |
| Integrated overtemperature shutdown | Automatically disables output above junction temperature threshold (~150°C), preventing thermal runaway in sealed enclosures. |
| Load-dump tolerant design | Withstands ISO 7637-2 Pulse 5a (42 V, 100 ms) without external TVS or Zener, simplifying BOM for 24 V commercial vehicle ECUs. |
| Low-jitter digital output | 0.35 µs typical propagation delay variation ensures deterministic timing for microcontroller edge-triggered interrupts in real-time motor control. |
| Reverse polarity hardened input | Survives −18 V applied to VDD for >100 ms, eliminating need for series diode in battery-connected modules. |
Applications
| Power Window Lift Control | Seat Position Indexing |
|---|---|

IC Role / Device Role / Timing Role: High-stability magnetic latch delivering repeatable pulse timing to compare against expected motor phase period. Use Value: Integrated overcurrent/overtemperature protection prevents latch damage during repeated stall events, extending field lifetime beyond 100,000 cycles. |
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-REEL | BOP/BRP = ±3.5 mT; 5 V only supply; no load-dump tolerance; 1.2 µs jitter | Limited to low-voltage consumer appliances; unsuitable for 12 V/24 V automotive rails | Select only for cost-sensitive non-automotive designs where supply is regulated and magnetic field strength is weak. |
| Allegro A1220LUA-T | BOP/BRP = ±15 mT; 4.5–24 V supply; no reverse polarity rating; 0.5 µs jitter | Higher threshold reduces sensitivity to stray fields but requires stronger magnets; lacks −18 V reverse protection | Prefer for industrial encoders with large air gaps; avoid in battery-reverse-prone automotive service environments. |
Compared with US1881EUA-ABA-000-REEL and A1220LUA-T, TLV49613MXTMA1 uniquely combines automotive-grade supply robustness (3–32 V, −18 V reverse, 42 V load-dump), ultra-low jitter (0.35 µs), and tight ±7.5 mT thresholds - making it optimal for precision motion feedback in safety-critical vehicle subsystems.

FAQ
What is the maximum allowable supply voltage transient the TLV49613MXTMA1 can withstand?
The TLV49613MXTMA1 sustains 42 V transients for up to 100 ms without external components, complying with ISO 7637-2 Pulse 5a for 24 V systems. This eliminates the need for external TVS diodes in load-dump protection circuits, reducing bill-of-materials cost and PCB area in automotive ECU designs.
Does TLV49613MXTMA1 require an external pull-up resistor on its output pin?
Yes - the Q pin is an open-drain output and requires an external pull-up resistor to a logic-compatible voltage (e.g., 3.3 V or 5 V). Typical values range from 1 kΩ to 10 kΩ depending on rise time and bus capacitance; no internal pull-up is integrated.
How does the TLV49613MXTMA1 handle temperature-induced magnetic threshold drift?
It uses active error compensation and chopper stabilization to limit BOP/BRP drift to ±0.1 mT/°C over −40°C to +85°C. Measured hysteresis remains stable at 15 mT (typ.), ensuring consistent switching margins across operating temperatures without firmware correction.
Can TLV49613MXTMA1 be used in AEC-Q100 qualified automotive modules?
Yes - TLV49613MXTMA1 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient), with tested performance across −40°C to +85°C junction temperature. Its reverse polarity, load-dump, and ESD robustness meet automotive reliability standards for body electronics applications.
