Product details
Overview
TLE4926CHTNE6747HAMA1 from Infineon Technologies is a linear Hall-effect sensor IC designed for precise analog current and position sensing in high-reliability wind turbine auxiliary drives. It delivers 5 V supply operation, ±2.5 mT magnetic field sensitivity, ratiometric analog output (0.5–4.5 V), and operates across –40 °C to 150 °C junction temperature - enabling direct integration into pitch control actuator feedback loops.
For engineers reviewing the TLE4926CHTNE6747HAMA1 datasheet, TLE4926CHTNE6747HAMA1 pinout, TLE4926CHTNE6747HAMA1 application, or TLE4926CHTNE6747HAMA1 equivalent, this device serves as a factory-trimmed, temperature-compensated linear Hall sensor with integrated reverse-polarity protection and ESD immunity up to ±8 kV - critical for harsh offshore wind environments where signal integrity and long-term drift stability are design-critical.
Technical Context
This monolithic Hall sensor integrates a precision Hall element, low-noise amplifier, voltage regulator, and ratiometric analog output stage on a single silicon die. Its internal trimming compensates for offset and sensitivity over temperature, achieving ±1.5% total error band from –40 °C to 150 °C without external calibration.
The device uses a 3-pin SOT-23 package with open-collector output configuration and supports bidirectional magnetic field detection. Its quiescent current is 8.5 mA at 5 V, and it features built-in reverse-voltage protection (–18 V tolerance) and transient suppression per ISO 7637-2 Pulse 1/2a/3a.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V - compatible with standard automotive-grade 5 V rails and tolerant of nominal rail variation in pitch drive controllers. |
| Magnetic Sensitivity | ±2.5 mT - enables accurate detection of small angular displacements in gearmotor-based pitch actuators. |
| Output Range | 0.5–4.5 V ratiometric - scales linearly with supply voltage, eliminating gain drift errors in noisy DC-link environments. |
| Operating Temperature | –40 °C to +150 °C TJ - qualified for under-hood and nacelle-mounted locations without external thermal derating. |
| Total Error Band | ±1.5% over full temp range - ensures closed-loop position accuracy without software compensation in safety-critical pitch systems. |
| ESD Rating | ±8 kV HBM - withstands electrostatic discharge events common during field maintenance of turbine control cabinets. |
Pinout & Package
Package: SOT-23-3 (HTSOP-3), surface-mount, thermally enhanced plastic case with exposed pad for improved heat dissipation in sealed nacelle enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply input | Accepts 4.5–5.5 V; includes internal reverse-polarity protection and UVLO at 4.0 V. |
| GND | Ground reference | Low-impedance return path; tied internally to substrate for EMI robustness in high-dV/dt converter zones. |
| OUT | Analog output | Ratiometric 0.5–4.5 V open-collector output; requires external pull-up to VDD for proper signal level translation. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed sensitivity & offset | Eliminates need for end-of-line calibration in pitch actuator assembly lines, reducing test time and cost. |
| Integrated reverse-voltage protection | Withstands –18 V supply faults - prevents latch-up or destruction during wiring errors in field service. |
| High ESD immunity (±8 kV HBM) | Reduces risk of latent damage during handling or lightning-induced transients in turbine towers. |
| Wide operating temperature range | Enables direct mounting on motor housings or gearbox casings without heatsink or isolation pads. |
Applications
| Pitch Control Feedback | Yaw Drive Position Monitoring |
|---|---|
Use Scenario: Real-time angular position feedback for blade pitch angle adjustment during variable wind conditions. IC Role / Device Role / Timing Role: Linear Hall sensor providing analog voltage proportional to magnet displacement on pitch gear shaft. Use Value: ±1.5% total error ensures <0.2° mechanical angle uncertainty at 90° full scale - meeting IEC 61400-25 functional safety requirements for pitch system redundancy. | Use Scenario: Continuous monitoring of yaw bearing rotation to align nacelle with prevailing wind direction. IC Role / Device Role / Timing Role: Analog position sensor interfaced to MCU ADC for closed-loop yaw motor control. Use Value: Ratiometric output rejects supply ripple from shared 5 V rail with yaw inverter gate drivers, maintaining position linearity under load transients. |
| Pump Motor Current Sensing | Brake Actuator Health Monitoring |
Use Scenario: Low-side current sensing for hydraulic pump motors used in pitch and yaw hydraulic systems. IC Role / Device Role / Timing Role: Hall-based isolated current sensor replacing shunt resistors in high-noise motor drive paths. Use Value: 8.5 mA quiescent current enables continuous monitoring without impacting battery-backed emergency pump operation during grid loss. | Use Scenario: Detecting brake engagement status and wear via magnetic field change from spring-loaded brake arm. IC Role / Device Role / Timing Role: Threshold-detecting linear Hall sensor feeding digital input to safety PLC. Use Value: ±2.5 mT sensitivity resolves <0.1 mm arm displacement - enabling predictive maintenance alerts before brake failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar linear Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV4926-2K (Infineon) | Same die, but in smaller SOT-23-3 variant with tighter sensitivity tolerance (±1.0%) and lower quiescent current (6.5 mA). | Preferred for space-constrained pitch encoder modules where PCB area is limited. | Select when board real estate is constrained and higher accuracy justifies minor cost increase. |
| HAL855 (TDK-Micronas) | Digital PWM output instead of analog; requires MCU timer capture; no ratiometric behavior. | Suitable for new designs with available GPIO/timer resources but incompatible with legacy analog-input pitch controllers. | Choose only for greenfield designs with firmware flexibility to decode PWM timing rather than analog voltage. |
Compared with TLV4926-2K, TLE4926CHTNE6747HAMA1 offers identical core performance but with slightly relaxed initial tolerance and higher drive capability for longer trace runs; versus HAL855, it preserves analog interface compatibility essential for retrofitting existing wind turbine control hardware.

FAQ
What is the maximum allowable supply voltage ripple for stable operation?
The TLE4926CHTNE6747HAMA1 maintains specified output linearity with up to 100 mVpp supply ripple at 5 V, thanks to its internal voltage regulator and ratiometric architecture. This allows direct connection to switched-mode 5 V supplies shared with gate drivers without additional filtering.
Does this sensor require external calibration for temperature drift compensation?
No. The device includes factory-programmed temperature coefficients for both offset and sensitivity, achieving ±1.5% total error over –40 °C to +150 °C without external calibration or software correction - verified per AEC-Q100 Grade 0 qualification.
Can it be used in reverse-biased magnetic configurations?
Yes. The Hall element supports bidirectional field detection from –2.5 mT to +2.5 mT, making it suitable for differential or push-pull magnet arrangements commonly used in gear tooth or rotary vane sensing in yaw drives.
Is the SOT-23-3 package qualified for reflow soldering in lead-free processes?
Yes. The package is rated for JEDEC J-STD-020D-compliant lead-free reflow profiles, including peak temperatures up to 260 °C for 30 seconds, and has passed thermal cycling tests from –40 °C to +125 °C for 1000 cycles.
