Product details
Overview
TLE49613MXTSA1 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 ±7.5 mT magnetic switching thresholds (BOP/BRP), 0.35 µs typical output jitter, -40°C to +170°C operating temperature, and open-drain output - enabling direct interface with pole-wheel-based index counting in window lifters and power-closing actuators.
For engineers reviewing the TLE49613MXTSA1 datasheet, TLE49613MXTSA1 pinout, TLE49613MXTSA1 application, or TLE49613MXTSA1 equivalent, key selection criteria include magnetic threshold stability over temperature, load-dump resilience (42 V overvoltage capability), reverse polarity protection (-18 V), and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE49613MXTSA1 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 enables stable operation across wide input voltage swings, while active error compensation maintains threshold accuracy over temperature.
Functional block includes overtemperature and overcurrent protection circuitry tied to the output stage, and sequencer-controlled startup ensures deterministic initialization. The device outputs a clean, jitter-minimized open-drain signal synchronized to magnetic field polarity reversal - critical for reliable edge detection in rotating target applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 32 V - supports direct connection to automotive battery without external regulation; tolerates 42 V load-dump transients without external resistor. |
| Magnetic Operating Point (BOP) | +7.5 mT (typ.) - precise north-pole activation threshold for repeatable latching at defined angular positions. |
| Magnetic Release Point (BRP) | -7.5 mT (typ.) - symmetric south-pole release point ensuring consistent hysteresis and immunity to field noise. |
| Output Jitter | 0.35 µs (typ.) - enables sub-degree angular resolution in high-speed rotation sensing (e.g., >10,000 rpm). |
| Operating Temperature | -40°C to +170°C - qualified for engine bay, transmission, and brake actuator environments per AEC-Q100 Grade 0. |
| ESD Protection | ±4 kV HBM - robust handling during SMT assembly and in-field service without additional protection circuitry. |
| Reverse Polarity Protection | -18 V - survives incorrect battery connection without damage or latch-up. |
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 derives bias for all analog/digital blocks; withstands -18 V reverse and +42 V transients. |
| 2 - Q | Open-drain output | Sinks current when active (latched); requires external pull-up; supports 20 mA max sink current with thermal foldback. |
| 3 - GND | Ground reference | Common return for supply and output; connects to substrate and thermal pad for enhanced thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Chopper-stabilized Hall sensing | Eliminates offset drift and 1/f noise, enabling <±0.2 mT threshold variation over full temperature range. |
| Integrated overtemperature protection | Shuts down output above 180°C junction temperature and auto-recovers upon cooling - prevents thermal runaway in sealed actuators. |
| Load-dump resilient design | No external clamping required for ISO 7637-2 Pulse 5a (42 V, 400 ms) - reduces BOM count and PCB area in automotive ECUs. |
| High ESD robustness | ±4 kV HBM rating allows direct handling on production lines without special ESD controls beyond standard IPC-610 requirements. |
| Low-power operation | 1.6 mA supply current at 5 V enables always-on sensing in battery-powered modules with multi-year standby life. |
Applications
| Power Window Lift Control | Seat Position Sensing |
|---|---|
|
Use Scenario: Detecting gear tooth or pole wheel rotation during motor-driven window ascent/descent to prevent pinch detection failure. IC Role / Device Role / Timing Role: Bipolar latch providing edge-triggered digital feedback synchronized to mechanical position - used for real-time speed and direction monitoring.

IC Role / Device Role / Timing Role: High-stability Hall latch delivering precise rising/falling edges aligned to crank tooth edges - fed into dedicated timer capture peripheral. Use Value: 42 V overvoltage tolerance handles alternator load-dump events without protection diodes; low jitter preserves timing accuracy at 8,000 rpm. |
Use Scenario: Detecting P/R/N/D gear positions in electronic shift-by-wire systems using magnet-embedded selector lever. IC Role / Device Role / Timing Role: Latching sensor confirming mechanical detent engagement - provides fail-safe position confirmation independent of motor encoder. Use Value: Reverse polarity protection (-18 V) prevents damage during battery jump-start scenarios; AEC-Q100 Grade 0 qualification ensures reliability in safety-critical shifting logic. |
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 | Wider BOP/BRP spread (±10 mT vs ±7.5 mT); lower temp range (-40°C to +150°C); no load-dump tolerance beyond 36 V. | Lacks AEC-Q100 Grade 0 rating; unsuitable for under-hood crank sensing where 170°C ambient occurs. | Select only for cost-sensitive cabin applications where 150°C max ambient suffices and tighter threshold matching is not required. |
| NXP SL100100A | Higher supply current (2.3 mA); asymmetric thresholds (+8.5 mT / -6.0 mT); no reverse polarity protection. | Requires external TVS and reverse-blocking diode - increases BOM and layout complexity in space-constrained modules. | Prefer only when legacy NXP ecosystem integration outweighs added protection circuitry and thermal margin loss. |
Compared with US1881EUA-ABA-000-RE and SL100100A, TLE49613MXTSA1 delivers superior thermal margin, tighter magnetic symmetry, and integrated protection - reducing system-level validation effort for AEC-Q100-compliant automotive designs.

FAQ
What is the maximum allowable supply voltage transient for TLE49613MXTSA1?
The device withstands 42 V load-dump transients per ISO 7637-2 Pulse 5a for up to 400 ms without external protection components. This is validated in the datasheet Section 3.2 (Absolute Maximum Ratings) and confirmed by test reports referenced in Revision 1.2 (2019-12-20). Operation above 32 V is permitted only during transient conditions - continuous operation must remain within 3.0 V to 32 V.
Does TLE49613MXTSA1 require an external pull-up resistor on the Q pin?
Yes - the Q pin is an open-drain output and requires an external pull-up resistor to VDD or another logic-compatible voltage. Typical values range from 2.2 kΩ to 10 kΩ depending on rise time and bus capacitance. Figure 7 and Figure 8 in the datasheet show both configurations: with and without external resistor, though the latter assumes internal weak pull-up is insufficient for most timing-critical applications.
How does the chopper stabilization improve performance over conventional Hall latches?
Chopper stabilization modulates the Hall sensor signal at ~100 kHz and demodulates it downstream, eliminating DC offset drift and low-frequency noise. This yields ±0.2 mT threshold variation over -40°C to +170°C - compared to ±1.5 mT in non-chopped devices - enabling reliable latching in high-temperature engine environments without recalibration.
Is TLE49613MXTSA1 pin-compatible with earlier TLE4961 variants?
Yes - TLE49613MXTSA1 uses the same PG-SOT23-3-15 package and identical pinout (VDD–Q–GND) as TLE4961-2M and TLE4961-3M. Electrical characteristics including BOP/BRP, jitter, and protection features are identical; only ordering code and date-code marking differ per Infineon's SP000909960 specification.
