Product details
Overview
TLE49614MXTMA1 from Infineon Technologies is a bipolar Hall effect latch IC designed for high-precision position sensing in automotive powertrain and body electronics. It operates from 3.0 V to 32 V supply, features ±10 mT magnetic switching thresholds (BOP/BRP), 0.35 µs typical output jitter, open-drain output, and AEC-Q100 qualified operation from −40°C to +170°C - enabling robust index counting with pole wheels in window lifters and power closing systems.
For engineers reviewing the TLE49614MXTMA1 datasheet, TLE49614MXTMA1 pinout, TLE49614MXTMA1 application, or TLE49614MXTMA1 equivalent, key selection criteria include magnetic threshold stability over temperature, load-dump tolerance up to 42 V, reverse polarity protection (−18 V), integrated overcurrent/overtemperature protection, and SOT23-3 footprint compatibility for space-constrained automotive modules.
Technical Context
The TLE49614MXTMA1 integrates a spinning Hall probe with chopper-stabilized amplifier, demodulator, low-pass filter, and comparator with hysteresis - delivering stable BOP/BRP of ±10 mT across −40°C to +170°C with <±0.2 mT/°C drift. Its voltage regulator supports direct connection to unregulated 12 V/24 V vehicle batteries, while active error compensation corrects offset and thermal drift in real time.
Functional block sequencing includes oscillator-driven chopping, bias and compensation circuitry for DC offset cancellation, and integrated protection logic that disables output during overtemperature or output short-circuit events. The open-drain output drives external pull-up resistors up to 42 V, eliminating need for external clamping components during load-dump transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 32 V - enables direct connection to automotive battery rails without pre-regulation |
| Magnetic BOP / BRP | ±10 mT typ. - precise latching at defined north/south field polarity for reliable pole-wheel edge detection |
| Output Jitter | 0.35 µs typ. - ensures timing accuracy in high-speed rotational counting (e.g., >10 kHz wheel events) |
| Operating Temp | −40°C to +170°C - qualified for under-hood and transmission-mounted applications |
| ESD Protection | ±8 kV HBM - eliminates need for external TVS in most automotive PCB layouts |
| Overvoltage Withstand | 42 V - survives ISO 7637-2 Load Dump pulse without external resistor or Zener clamp |
| Reverse Polarity | −18 V - protects against battery misconnection during service or assembly |
Pinout & Package
Delivered in PG-SOT23-3-15 package: surface-mount, 3-pin, lead-free, RoHS-compliant small-outline transistor outline with exposed thermal pad (not electrically connected). Dimensions: 2.9 mm × 1.3 mm × 1.0 mm (L × W × H), pitch 0.95 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Positive supply input | Accepts 3.0–32 V DC; internal regulator powers all analog/digital blocks; withstands 42 V transient |
| 2 - Q | Open-drain output | Sinks current when active (low); requires external pull-up; supports up to 42 V pull-up voltage |
| 3 - GND | Ground reference | Return path for supply and output current; connects to PCB ground plane for EMI suppression |
Key Features
| Feature | Design Value |
|---|---|
| Chopper-stabilized Hall sensing | Reduces offset drift to <0.2 mT/°C - maintains ±10 mT BOP/BRP stability across full temperature range |
| Integrated overcurrent protection | Auto-recovering shutdown limits output sink current to prevent damage during short-to-ground faults |
| Active temperature compensation | Real-time correction of magnetic threshold shift - eliminates need for system-level calibration |
| Load-dump tolerant design | Withstands 42 V transients per ISO 7637-2 without external components - reduces BOM count and layout area |
| Reverse polarity protection | Operates safely after −18 V supply reversal - prevents latch damage during battery jump-start or replacement |
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 |
|---|---|---|---|
| Melexis US1881EUA-ABA-000-RE | BOP/BRP ±12 mT; max supply 24 V; no load-dump tolerance beyond 28 V | Lacks 42 V transient rating and AEC-Q100 Grade 0 qualification | Preferred for cost-sensitive non-safety-critical interior modules where 24 V rail and −40°C to +125°C suffice |
| Allegro A1220LUA-T | BOP/BRP ±15 mT; supply 3.5–24 V; 6 kV HBM ESD; no reverse polarity protection | Lower temp range (−40°C to +150°C); requires external reverse-battery diode | Used where higher magnetic sensitivity is needed but load-dump immunity and extended temperature are not required |
Compared with US1881EUA-ABA-000-RE and A1220LUA-T, the TLE49614MXTMA1 uniquely combines 42 V load-dump survival, −18 V reverse polarity tolerance, and full AEC-Q100 Grade 0 qualification - making it the only choice for under-hood crankshaft or transmission position sensing where system-level fault resilience is mandatory.

FAQ
What is the maximum allowable supply voltage transient the TLE49614MXTMA1 can withstand?
The TLE49614MXTMA1 is rated for 42 V absolute maximum supply voltage per ISO 7637-2 Load Dump Pulse Test, meaning it survives 42 V transients for up to 400 ms without external protection components. This eliminates the need for series resistors or Zener clamps in standard 12 V/24 V automotive designs.
Does the TLE49614MXTMA1 require an external pull-up resistor on the Q output?
Yes - the Q pin is an open-drain output and must be pulled up externally. The device supports pull-up voltages up to 42 V, allowing direct connection to battery rails. Typical values range from 2.2 kΩ to 10 kΩ depending on rise time and noise immunity requirements.
How does the TLE49614MXTMA1 achieve stable magnetic thresholds over temperature?
It uses a spinning Hall probe architecture combined with chopper stabilization and active bias compensation circuits. These techniques reduce offset drift to <±0.2 mT/°C, maintaining BOP and BRP within ±10 mT across −40°C to +170°C without external calibration.
Is the TLE49614MXTMA1 pin-compatible with earlier TLE496x variants?
Yes - it shares identical PG-SOT23-3-15 package, pinout (VDD–Q–GND), and functional behavior with TLE4961-2M and TLE4961-3M. Differences are limited to magnetic threshold tuning (±10 mT vs. ±15 mT or ±20 mT) and minor electrical parameter optimizations.
