Product details
Overview
TLE49615MXTSA1 from Infineon Technologies is a bipolar Hall effect latch IC designed for high-precision position and speed sensing in automotive powertrain and chassis systems. It operates from 3.0 V to 32 V supply, features ±15 mT magnetic 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-pulse detection on ferrous pole wheels.
For engineers reviewing the TLE49615MXTSA1 datasheet, TLE49615MXTSA1 pinout, TLE49615MXTSA1 application, or TLE49615MXTSA1 equivalent, key selection criteria include magnetic threshold stability over temperature, load-dump tolerance up to 42 V, reverse polarity protection, integrated overcurrent/overtemperature protection, and SOT23-3 package compatibility with high-vibration automotive PCB layouts.
Technical Context
The TLE49615MXTSA1 integrates a spinning Hall probe with chopper-stabilized amplifier, demodulator, low-pass filter, and comparator with hysteresis - delivering stable switching at ±15 mT with <±0.5 mT effective noise over temperature. Its internal voltage regulator enables direct connection to unregulated 12 V/24 V vehicle batteries.
Startup behavior includes active error compensation and controlled power-on timing (tPON ≤ 100 µs). The open-drain output supports external pull-up to voltages up to 32 V and delivers ≥10 mA sink current while maintaining <0.4 V saturation voltage at IOUT = 10 mA and TA = 150 °C.
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 transients (up to 42 V without external resistor) |
| Magnetic Thresholds | BOP = +15 mT, BRP = −15 mT - precise, symmetric latching for reliable pole-wheel edge detection with 30 mT hysteresis |
| Output Type | Open-drain N-channel MOSFET - enables flexible interface to microcontroller GPIO or higher-voltage logic with external pull-up |
| Operating Temperature | −40 °C to +170 °C - qualified per AEC-Q100 Grade 0 for under-hood engine control, transmission, and brake modules |
| Output Jitter | Typ. 0.35 µs - ensures sub-degree angular resolution in crankshaft/camshaft position sensing at >10,000 RPM |
| ESD Robustness | ±8 kV HBM - eliminates need for external TVS diodes in most automotive PCB layouts |
| Supply Current | 1.6 mA at VDD = 12 V, TA = 25 °C - enables low-power always-on sensing in start-stop systems |
Pinout & Package
Delivered in PG-SOT23-3-15 package: surface-mount, 3-pin, lead-free, RoHS-compliant, 1.45 mm × 0.65 mm body size, 0.95 mm max height, thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Positive supply input | Accepts 3.0–32 V DC; internal regulator powers all circuitry; reverse polarity protected to −18 V |
| 2 - Q | Open-drain output | Sinks current when active (logic LOW); requires external pull-up; rated for 10 mA sink, 32 V max pull-up voltage |
| 3 - GND | Ground reference | Return path for supply and output current; must be low-impedance connection to minimize EMI susceptibility |
Key Features
| Feature | Design Value |
|---|---|
| Active error compensation | Real-time offset cancellation via spinning Hall element and chopper stabilization - maintains ±0.5 mT threshold drift over full temperature range |
| Overvoltage capability | Withstands 42 V transients without external series resistor - simplifies design for 24 V commercial vehicle systems |
| Integrated protection | Automatic shutdown during overtemperature (>170 °C) or output overcurrent (>15 mA) - prevents latch failure during fault conditions |
| High ESD performance | ±8 kV HBM rating - meets ISO 10605 requirements without additional board-level protection components |
| Low-jitter timing | 0.35 µs typical output jitter - enables accurate time-of-arrival measurement for high-speed rotational 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-002-SP | Wider BOP/BRP spread (±25 mT), higher supply current (3.5 mA), no integrated overvoltage protection beyond 24 V | Lacks 42 V load-dump tolerance and Grade 0 temperature rating - limited to cabin or lower-temperature chassis use | Select when cost sensitivity outweighs under-hood robustness requirements and ±25 mT thresholds better match target magnet strength |
| NXP SL15010HTK | Unipolar operation only (BOP = +10 mT, BRP = 0 mT), no reverse polarity protection, 125 °C max junction temperature | Not suitable for bidirectional rotation sensing or high-temperature engine bay mounting | Choose only for non-automotive industrial encoders where unidirectional sensing and lower ambient temperatures apply |
Compared with US1881EUA-ABA-002-SP and SL15010HTK, the TLE49615MXTSA1 uniquely combines AEC-Q100 Grade 0 qualification, 42 V transient tolerance, reverse polarity protection, and symmetric ±15 mT thresholds - making it the only option validated for direct replacement in critical engine and transmission timing circuits.

FAQ
What is the maximum allowable supply voltage transient the TLE49615MXTSA1 can withstand?
The TLE49615MXTSA1 withstands load-dump transients up to 42 V for 400 ms without external protection components, per ISO 7637-2 Pulse 5a testing. This is enabled by its internal overvoltage clamp structure and eliminates the need for series resistors or TVS diodes in standard 12 V/24 V automotive designs.
Does the TLE49615MXTSA1 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-high voltage (≤32 V). Typical values range from 2.2 kΩ to 10 kΩ depending on rise-time requirements and bus capacitance; no internal pull-up is integrated.
How does the TLE49615MXTSA1 achieve stable magnetic thresholds across temperature?
It uses a spinning Hall plate architecture combined with chopper stabilization and active offset compensation circuitry. This reduces thermal drift of BOP and BRP to ±0.5 mT over −40 °C to +170 °C, verified in production test across temperature sweeps per AEC-Q100 stress profiles.
Can the TLE49615MXTSA1 be used in bidirectional rotation sensing applications?
Yes - its symmetric ±15 mT bipolar thresholds allow reliable detection of both north and south magnetic poles, enabling unambiguous direction determination when paired with dual-latch configurations or quadrature arrangements using two devices and a multi-pole ring magnet.
