Product details
Overview
TLE49655MXTSA1 from Infineon Technologies is a high-precision unipolar Hall effect switch optimized for automotive position sensing, featuring BOP = 7.5 mT, BRP = 5.0 mT, ±0.3 mT magnetic threshold accuracy over −40°C to +170°C, open-drain output, and AEC-Q100 qualification. It operates from 3.0 V to 5.5 V supply with 1.5 mA typical current consumption and 0.28 µs typical propagation delay jitter.
For engineers reviewing the TLE49655MXTSA1 datasheet, TLE49655MXTSA1 pinout, TLE49655MXTSA1 application, or TLE49655MXTSA1 equivalent, key selection criteria include magnetic threshold stability at 170°C, ESD robustness (4 kV HBM), SOT23-3 package compatibility, and unipolar switching behavior in safety-critical vehicle subsystems.
Technical Context
The TLE49655MXTSA1 integrates a spinning Hall probe with chopper-stabilized amplifier, demodulator, low-pass filter, and comparator with 2.5 mT hysteresis to suppress noise-induced false triggering. Its internal voltage regulator enables stable operation across 3.0–5.5 V input while maintaining magnetic threshold drift < ±0.01 mT/°C.
It uses active error compensation to correct offset and sensitivity drift over temperature and lifetime. The device powers up with defined default state (output high-impedance until valid supply and magnetic field conditions are met) and supports direct connection to microcontroller GPIOs via open-drain interface with pull-up resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 5.5 V - compatible with standard automotive 3.3 V and 5 V regulated rails |
| Operating Temp | −40°C to +170°C - qualified for under-hood and transmission-mounted applications |
| BOP / BRP | 7.5 mT / 5.0 mT - precise unipolar switching with 2.5 mT hysteresis prevents chatter near threshold |
| Output Type | Open-drain - allows wired-OR configuration and flexible pull-up voltage selection |
| Jitter | 0.28 µs typ - ensures deterministic timing for high-speed gear tooth or cam detection |
| ESD Rating | 4 kV HBM - meets automotive system-level ESD immunity requirements without external protection |
| Supply Current | 1.5 mA typ - enables low-power always-on sensing in battery-constrained modules |
Pinout & Package
Package: PG-SOT23-3-15 - surface-mount plastic package with 0.95 mm body height, 2.9 mm × 1.3 mm footprint, and lead pitch of 0.95 mm; RoHS-compliant, halogen-free, and qualified per AEC-Q200.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Positive supply input | Accepts 3.0–5.5 V regulated rail; internal regulator supplies bias to all analog blocks |
| 2 (Q) | Open-drain output | Sinks current when active; requires external pull-up to define logic-high level and drive strength |
| 3 (GND) | Ground reference | Return path for supply and output current; must be low-impedance connection to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Spinning Hall probe | Eliminates offset drift and enables < ±0.01 mT/°C thermal stability of BOP/BRP |
| Chopper-stabilized amplifier | Reduces 1/f noise and input offset to support sub-mT resolution in noisy environments |
| Active error compensation | Corrects for process variation and aging effects to maintain threshold accuracy over 15+ year life |
| Defined start-up behavior | Output remains high-impedance until VDD > 2.7 V and internal regulation stabilizes (~100 µs) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unipolar Hall switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL33030EUA-7 | BOP = 8.0 mT, BRP = 5.5 mT; no integrated voltage regulator - requires external 3.3 V supply | Lower temp max (+150°C); lacks AEC-Q100 Grade 0 validation | Prefer where cost sensitivity outweighs extended temperature and qualification needs |
| US5881LUA-7 | BOP = 6.5 mT, BRP = 4.0 mT; higher hysteresis (2.5 mT same), but 3.5 µs max propagation delay vs. 1.2 µs typ for TLE49655MXTSA1 | Rated only to +125°C; not qualified for automotive powertrain locations | Select only for non-safety-critical cabin or body applications with relaxed timing and temp requirements |
Compared with AL33030EUA-7 and US5881LUA-7, the TLE49655MXTSA1 delivers tighter magnetic thresholds, guaranteed 170°C operation, and integrated regulation-making it the sole choice for transmission, brake, and steering lock systems requiring zero-field reliability and long-term stability.

FAQ
What is the magnetic field polarity requirement for TLE49655MXTSA1 operation?
The TLE49655MXTSA1 is a unipolar Hall switch that responds only to the south pole of a magnet approaching the marked side of the package (top surface, center of sensitive area). It activates when flux density exceeds +7.5 mT (BOP) and deactivates at +5.0 mT (BRP); north-pole fields produce no response. Magnetic field direction is defined per Figure 8 in the datasheet.
Can TLE49655MXTSA1 operate directly from a 12 V automotive battery?
No - the device requires a regulated supply between 3.0 V and 5.5 V. Direct 12 V connection will exceed absolute maximum ratings and cause permanent damage. It must be powered via an LDO or DC-DC converter delivering stable 3.3 V or 5 V, as specified in Section 3.2 of the datasheet.
Is external ESD protection required for TLE49655MXTSA1 in automotive harness interfaces?
No - the device incorporates 4 kV HBM ESD protection on all pins, satisfying ISO 10605 and AEC-Q100 stress test requirements. External TVS diodes are unnecessary unless system-level transients exceed 4 kV contact discharge, which is uncommon in properly designed automotive PCB layouts.
How does the TLE49655MXTSA1 handle power supply ramp-up during cold cranking?
During cold cranking, VDD may dip below 2.7 V before recovering. The device enters undervoltage lockout (UVLO) and holds Q in high-impedance state until VDD rises above 2.7 V and internal regulation stabilizes (~100 µs), preventing false output transitions. This behavior is documented in Figure 6 and Section 2.6 of the datasheet.
