Product details
Overview
TLE49595USPHALA1 from Infineon Technologies is a Hall-based differential speed sensor IC designed for automotive transmission speed sensing. It delivers rotational speed information to transmission control units using three integrated Hall elements, features adaptive hysteresis (typ. 1/8 × Bpp), operates over ±120 mT magnetic dynamic range, and supports 0–10 kHz signal frequency with AEC-Q100 qualification and PG-SSO-4-1 packaging.
For engineers reviewing the TLE49595USPHALA1 datasheet, TLE49595USPHALA1 pinout, TLE49595USPHALA1 application, or TLE49595USPHALA1 equivalent, key selection criteria include vibration-suppressed output timing, large airgap tolerance (>2 mm typical), uncalibrated/calibrated mode switching behavior, and 4.0–16 V supply compatibility in 12 V automotive systems.
Technical Context
The device implements a self-calibrating digital core that continuously tracks magnetic input via a Tracking ADC, computes offset correction from dual extrema, and switches between uncalibrated (DNC-triggered) and calibrated (adaptive hysteresis–triggered) operation modes. Its direction channel digitizes center-Hall signals to detect 90° phase shift relative to speed bridge zero crossings.
Vibration suppression relies on real-time correlation of magnetic amplitude and rotation direction data: parasitic signals induced by angular or airgap vibration are identified and cause output pulse suppression. The hysteresis threshold scales dynamically with peak-to-peak magnetic field (Bpp) and maintains ≥HYSmin under all conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.0–16 V continuous - compatible with standard 12 V automotive rails; requires external RSupply for overvoltage protection |
| Magnetic Frequency Range | 0–10 kHz - supports full-speed detection up to 600,000 RPM on 100-tooth wheels |
| Differential Magnetic Range | ±120 mT - enables robust operation across large mechanical airgaps and misalignments |
| Hysteresis Scaling | Typ. 1/8 × Bpp - adapts switching threshold to signal amplitude, suppressing noise/vibration without sacrificing edge fidelity |
| Junction Temp Range | −40 °C to +175 °C (2500 h) - qualified for under-hood transmission control environments |
| ESD Robustness | ±2 kV HBM - meets automotive EMC immunity requirements per ISO 10605 |
| Output Configuration | Open-drain N-channel - requires external RLoad (1.2 kΩ recommended for 5 V logic) |
Pinout & Package
Supplied in RoHS-compliant PG-SSO-4-1 package: surface-mount, 4-pin single-sided leadless package with exposed thermal pad, optimized for high-vibration automotive mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply input | 4.0–16 V rail; requires external series resistor RSupply for transient protection in 12 V systems |
| GND | Ground reference | Low-impedance return path for supply and output current; must be connected to chassis ground near sensor location |
| OUT | Open-drain output | Active-low speed pulse output; requires external pull-up (1.2 kΩ for 5 V) and drives ≤15 mA sink current |
| NC | No connect | Internally unused pin; must remain unconnected and unbonded per Infineon design |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic self-calibration | Real-time offset correction using dual magnetic extrema; eliminates manual calibration and drift-induced errors |
| Adaptive hysteresis | Threshold scales to 1/8 × Bpp; maintains clean edge detection across variable airgaps and temperature |
| Vibration suppression | Digital correlation of speed/direction channels identifies and suppresses false pulses from mechanical resonance |
| Large operating airgap | Supports >2 mm nominal airgap with ferromagnetic encoder wheels - reduces assembly tolerance sensitivity |
| Three-wire interface | VDD/GND/OUT configuration simplifies wiring harness routing and EMI filtering in transmission modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential Hall speed sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Melexis MLX92292ESE-AAA-000-RE | Dual-die Hall IC with programmable hysteresis; no built-in vibration suppression algorithm; requires external microcontroller for offset calibration | Lacks integrated vibration rejection; suitable only where mechanical isolation is guaranteed and firmware resources exist for calibration | Select when system-level processing is available and cost-per-node is prioritized over out-of-box robustness |
| NXP TLE4922CXTMA1 | Single-ended Hall sensor; fixed hysteresis (15 mT); no direction channel or self-calibration; lower magnetic sensitivity (±60 mT) | Cannot resolve direction or suppress vibration; limited to low-airgap, low-vibration applications like ABS wheel speed | Choose only for non-transmission use cases where cost and simplicity outweigh performance requirements |
Compared with MLX92292ESE and TLE4922CXTMA1, TLE49595USPHALA1 provides unique integration of adaptive hysteresis, real-time vibration suppression, and factory-calibrated differential sensing-enabling direct drop-in deployment in high-dynamic transmission environments without host MCU intervention.

FAQ
What is the purpose of the NC pin on TLE49595USPHALA1?
The NC (No Connect) pin is an unassigned terminal in the PG-SSO-4-1 package. It is not bonded internally and serves no electrical function. Per Infineon's design, it must remain unconnected and unpopulated on PCB layouts to avoid mechanical stress or unintended coupling.
Does TLE49595USPHALA1 require external capacitors for stable operation?
Yes - a 100 nF ceramic capacitor between VDD and GND is mandatory for EMC robustness, placed within 5 mm of the IC. In 12 V systems, a series supply resistor (RSupply) is also required to limit inrush current and absorb transients per Infineon's application guidance.
How does the adaptive hysteresis improve performance over fixed-threshold sensors?
Adaptive hysteresis scales to 1/8 × magnetic peak-to-peak amplitude, maintaining optimal noise margin across varying airgaps and temperature. This avoids false triggering at large gaps (where fixed hysteresis would be too coarse) and missed edges at small gaps (where it would be too tight).
Can TLE49595USPHALA1 detect rotational direction?
No - although it contains a dedicated direction channel using the center Hall element, the TLE49595USPHALA1 variant is factory-programmed to output speed pulses only. Direction capability exists in the silicon but is disabled in this part number; use TLE49595U-SP for dual-output variants.
