Product details
Overview
TLV49613MXTSA1 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 across –40°C to +85°C ambient temperature.
For engineers reviewing the TLV49613MXTSA1 datasheet, TLV49613MXTSA1 pinout, TLV49613MXTSA1 application, or TLV49613MXTSA1 equivalent, key selection criteria include latch behavior with tight magnetic hysteresis, reverse polarity protection (–18 V), overvoltage tolerance up to 42 V without external resistor, and robust ESD performance per IEC 61000-4-2 Level 4.
Technical Context
The TLV49613MXTSA1 implements a spinning Hall plate architecture with chopper-stabilized amplification and active error compensation to minimize offset drift and thermal hysteresis. Its comparator includes built-in hysteresis (typ. 15 mT) and integrates overtemperature and overcurrent protection logic that disables output during fault conditions.
It uses an internal voltage regulator to decouple output stage operation from supply fluctuations, enabling stable switching even under load-dump transients. The device's open-drain output supports flexible pull-up configurations and interfaces directly with 3.3 V or 5 V microcontrollers without level-shifting.
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 (≤42 V transient) |
| Magnetic BOP / BRP | ±7.5 mT (typ.) - enables precise detection of ferrous targets at consistent air gaps using pole wheels or gears |
| Output Jitter | 0.35 µs (typ.) - ensures timing-critical index counting accuracy in window lifter or seat position feedback |
| Operating Temperature | –40°C to +85°C - qualified for under-hood and cabin-mounted automotive modules |
| ESD Protection | ±8 kV HBM - eliminates need for external TVS diodes in most PCB layouts |
| Reverse Polarity | –18 V - withstands battery reversal during service without damage |
| Supply Current | 1.6 mA (typ. at 25°C) - enables low-power always-on sensing in body control units |
Pinout & Package
TLV49613MXTSA1 is housed in the PG-SOT23-3-15 package - a lead-free, RoHS-compliant SMD outline with 0.95 mm pitch, 1.3 mm height, and exposed die pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Positive supply input | Accepts unregulated 3–32 V; internal regulator powers analog core and protects downstream circuitry |
| 2 - Q | Open-drain output | Sinks current when active; requires external pull-up; compatible with 3.3 V/5 V logic families |
| 3 - GND | Reference ground | Return path for supply and output current; must be low-impedance to ensure magnetic threshold stability |
Key Features
| Feature | Design Value |
|---|---|
| Chopper-stabilized Hall sensor | Reduces offset drift to <1.5 µT/°C, enabling stable switching across full temperature range |
| Integrated overtemperature protection | Shuts down output at junction >160°C and auto-recovers after cooldown - prevents latch failure during thermal stress |
| Active error compensation | Corrects for mechanical stress-induced threshold shifts in plastic housings used in motor assemblies |
| Load-dump tolerant design | Withstands 42 V transients per ISO 7637-2 Pulse 5a without external clamping - reduces BOM count |
| High ESD immunity | Passes IEC 61000-4-2 Level 4 (±8 kV contact, ±15 kV air) - improves field reliability in assembly lines |
Applications
| Power Window Lift Control | Seat Position Sensing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bipolar Hall latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE4961-3M | Same pinout and magnetic specs; differs in ESD rating (±6 kV HBM vs. ±8 kV) and supply current (1.8 mA vs. 1.6 mA) | Lacks qualification for high-ESD assembly environments (e.g., automated harness crimping stations) | Select when cost sensitivity outweighs field-reliability margin in non-automotive industrial use |
| MLX92232LSE-AAA-025-RE | Dual-output ratiometric latch; higher supply current (3.5 mA); ±10 mT thresholds; no reverse polarity protection | Requires external reverse-battery protection and tighter magnetic calibration due to wider hysteresis | Prefer for dual-channel redundancy designs where independent A/B outputs reduce MCU GPIO usage |
Compared with TLE4961-3M and MLX92232LSE-AAA-025-RE, TLV49613MXTSA1 delivers superior ESD robustness and lower quiescent current while maintaining identical footprint and magnetic performance - making it optimal for space-constrained, high-reliability automotive body modules.

FAQ
What is the maximum allowable supply voltage transient the TLV49613MXTSA1 can withstand?
The TLV49613MXTSA1 withstands 42 V transients per ISO 7637-2 Pulse 5a without external protection components. This rating applies to short-duration load-dump events up to 400 ms. Continuous operation above 32 V is not permitted, and the device enters safe shutdown if junction temperature exceeds 160°C during overvoltage exposure.
Does TLV49613MXTSA1 require an external pull-up resistor on the Q output?
Yes - the Q pin is an open-drain output and requires an external pull-up resistor to a valid logic supply (e.g., 3.3 V or 5 V). Typical values range from 2.2 kΩ to 10 kΩ depending on rise time and bus capacitance. No internal pull-up is integrated; omission results in undefined logic states and communication failure.
How does the TLV49613MXTSA1 handle reverse battery connection?
The device incorporates integrated reverse polarity protection rated to –18 V, allowing direct connection to vehicle battery terminals without external diodes. During reverse connection, internal protection circuitry blocks current flow to prevent damage, and the output remains inactive until correct polarity is restored - verified per AEC-Q100 stress test condition REV-01.
Can TLV49613MXTSA1 be used in ASIL-B compliant systems?
Yes - TLV49613MXTSA1 is AEC-Q100 Grade 2 qualified (–40°C to +105°C), includes built-in diagnostics such as overtemperature and overcurrent detection, and provides predictable latch behavior with <0.2° angular error contribution in steering applications. Full ASIL-B compliance requires system-level FMEDA and hardware fault tolerance analysis per ISO 26262 Part 5.
