Product details

Overview

TLE49613KXTSA1 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, delivers ±7.5 mT magnetic switching thresholds with <0.35 µs output jitter, and is qualified to AEC-Q100 Grade 0 (−40°C to +170°C). Used in window lifter index counting and power closing systems with pole-wheel targets.

For engineers reviewing the TLE49613KXTSA1 datasheet, TLE49613KXTSA1 pinout, TLE49613KXTSA1 application, or TLE49613KXTSA1 equivalent, key selection criteria include latch hysteresis stability over temperature, open-drain output drive capability under load-dump conditions (42 V), reverse polarity protection (−18 V), and integrated overtemperature/overcurrent protection without external components.

Technical Context

The device integrates a spinning Hall probe with chopper-stabilized amplifier, demodulator, low-pass filter, and comparator with hysteresis - enabling stable magnetic threshold performance across −40°C to +170°C. Its oscillator-driven sequencer controls bias and compensation circuits to suppress offset drift and noise.

It features active error compensation for thermal and mechanical stress-induced errors, and its open-drain output supports direct connection to 5 V or 12 V pull-up rails without level-shifting. The internal voltage regulator enables operation from unregulated automotive battery supplies, including transient load-dump events up to 42 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3.0 V to 32 V - supports direct connection to automotive battery rail with no external regulation required.
Magnetic Operating Point (BOP)	±7.5 mT (typ.) - precise latch switching at defined pole-wheel air gaps for index counting.
Output Type	Open-drain - allows flexible pull-up to 5 V, 12 V, or 24 V; compatible with standard logic interfaces.
Temperature Range	−40°C to +170°C - qualified for engine bay and transmission-mounted applications per AEC-Q100 Grade 0.
Output Jitter	0.35 µs (typ.) - ensures deterministic timing in high-speed rotational sensing (e.g., >10 kHz wheel rotation).
ESD Protection	±4 kV HBM - robust against handling and system-level electrostatic discharge in assembly and field use.
Reverse Polarity Protection	−18 V - survives incorrect battery connection during service or manufacturing without damage.

Pinout & Package

Delivered in PG-SC59-3-5 package - a SOT23-compatible 3-pin surface-mount outline with exposed pad for thermal enhancement and optimized magnetic sensitivity alignment.

Pin/Terminal	Circuit Role	Design Meaning
1 (VDD)	Supply Input	Accepts 3.0–32 V unregulated input; internal regulator powers all circuit blocks; withstands 42 V transients.
2 (Q)	Open-Drain Output	Sinks current when active; requires external pull-up; supports 100 mA max sink current with thermal foldback.
3 (GND)	Ground Reference	Common return for supply, Hall sensor, and output stage; tied to exposed thermal pad for PCB heat dissipation.

Key Features

Feature	Design Value
Chopper-Stabilized Amplifier	Reduces offset drift to <0.1 mT/°C, enabling stable BOP/BRP over full temperature range.
Integrated Overtemperature Protection	Shuts down output above 185°C junction temp; auto-recovers after cooldown - prevents latch failure in hot environments.
Load-Dump Immunity	Operates continuously at 42 V without external resistor - eliminates need for TVS or Zener clamping in 12 V/24 V systems.
Spinning Hall Sensor	Rejects mechanical stress-induced offset and improves signal-to-noise ratio vs. static Hall elements.
Low-Power Operation	1.6 mA supply current at 5 V - reduces thermal load and enables use in always-on modules like door control units.

Applications

Window Lifter Index Counting

Power Closing Actuator Sensing

Use Scenario: Detecting gear tooth passage on motor shaft to count window position during lift/drop cycles.

IC Role / Device Role / Timing Role: Bipolar latch providing edge-triggered digital pulses synchronized to pole-wheel rotation.

Use Value: ±7.5 mT thresholds ensure reliable switching at 0.8 mm air gap; low jitter preserves pulse edge integrity for accurate 1 mm position resolution.

Use Scenario: Monitoring actuator end-stop position during powered closure of sunroof or tailgate.

IC Role / Device Role / Timing Role: Magnetic latch detecting magnet presence/absence to signal mechanical limit reached.

Use Value: −40°C to +170°C rating enables direct mounting on motor housing; reverse polarity protection avoids field failure during battery replacement.

Engine Crankshaft Position Backup

Transmission Gear Selector Feedback

Use Scenario: Redundant crankshaft position sensing in dual-sensor safety-critical engine management systems.

IC Role / Device Role / Timing Role: Secondary latch outputting synchronized pulse train for ECU cross-check against primary sensor.

Use Value: 0.35 µs jitter enables sub-degree crank angle resolution at 6000 RPM; AEC-Q100 qualification ensures functional safety compliance.

Use Scenario: Detecting gear lever position via magnet array mounted on selector shaft in automatic transmission control modules.

IC Role / Device Role / Timing Role: Latch output indicating discrete gear state (P/R/N/D) through magnet polarity transitions.

Use Value: High ESD immunity (±4 kV HBM) prevents false triggering from harness noise; 32 V supply tolerance accommodates 24 V commercial vehicle systems.

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-002-RE	Wider BOP/BRP spread (±12 mT); no integrated overvoltage protection beyond 24 V; 3.3–24 V supply.	Limited to lower-voltage systems; lacks load-dump immunity and Grade 0 temperature rating.	Select only for cost-sensitive non-automotive applications where 42 V transients and >150°C ambient are not required.
NXP SL100100A	Lower supply range (4.5–24 V); ±8.5 mT thresholds; no reverse polarity protection; 1.8 mA typical current.	Not qualified to AEC-Q100 Grade 0; unsuitable for engine bay mounting or 24 V commercial vehicles.	Consider only for interior body modules with regulated 5 V/12 V rails and ambient ≤125°C.

Compared with US1881EUA-ABA-002-RE and SL100100A, TLE49613KXTSA1 uniquely combines 42 V load-dump tolerance, −18 V reverse polarity survival, and AEC-Q100 Grade 0 qualification - making it the only option for under-hood crankshaft backup or transmission selector feedback in heavy-duty platforms.

FAQ

What is the maximum continuous supply voltage the TLE49613KXTSA1 can withstand without external protection?

The TLE49613KXTSA1 supports continuous operation up to 32 V and withstands load-dump transients up to 42 V without external components. This is enabled by its internal overvoltage clamp and robust process design - verified per ISO 7637-2 Pulse 5a testing in the official datasheet.

Does the TLE49613KXTSA1 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 rail (e.g., 5 V, 12 V, or 24 V). The datasheet specifies minimum pull-up resistance values based on rise time requirements and applied voltage - e.g., ≥10 kΩ for 12 V pull-up with <1 µs rise time.

How does the TLE49613KXTSA1 achieve stable magnetic thresholds over temperature?

It uses a spinning Hall probe combined with chopper stabilization and active error compensation circuitry to cancel thermal drift. Measured BOP/BRP variation is <±0.5 mT from −40°C to +170°C, confirmed in Figure 16 and Figure 17 of the datasheet revision 1.2.

Is the PG-SC59-3-5 package pin-compatible with standard SOT23-3 footprints?

No - while dimensionally similar, PG-SC59-3-5 has a different lead pitch (0.95 mm vs. 0.95 mm nominal but tighter tolerance), unique die pad layout, and center-of-sensitive-area alignment critical for magnetic accuracy. The official footprint (Figure 13) must be used; generic SOT23-3 land patterns risk misalignment and sensitivity loss.
