Product details

Overview

TLE4926CHTE6547HAMA1 from Infineon Technologies is a monolithic linear Hall-effect sensor IC designed for precise analog current and position sensing in high-reliability wind turbine auxiliary drives. It delivers ratiometric 0.5–4.5 V output over supply range 4.5–5.5 V, features ±1.5% total output error at 25°C, operates from –40°C to 150°C, and integrates on-chip temperature compensation and reverse-polarity protection.

For engineers reviewing the TLE4926CHTE6547HAMA1 datasheet, TLE4926CHTE6547HAMA1 pinout, TLE4926CHTE6547HAMA1 application, or TLE4926CHTE6547HAMA1 equivalent, this device is selected for demanding analog sensing in pitch/yaw drive feedback loops, DC-link current monitoring, and generator excitation control where thermal stability and ratiometric accuracy are critical.

Technical Context

The TLE4926CHTE6547HAMA1 implements a planar Hall plate with integrated signal conditioning, delivering a continuous analog voltage proportional to magnetic flux density perpendicular to the package surface. Its ratiometric architecture ties output span directly to supply voltage, eliminating sensitivity to V_CC drift in noisy power environments typical of wind turbine nacelles.

It uses a proprietary offset cancellation technique (chopping) to suppress low-frequency drift and 1/f noise, enabling stable DC-coupled operation without external capacitors. The device is qualified per AEC-Q100 Grade 0 and supports diagnostic functions including supply undervoltage detection and output clamping at rail limits.

Key Specifications

Parameter	Value and Actual Design Meaning

Output Range	0.5–4.5 V ratiometric - Provides full-scale headroom for ADC reference matching and fault margin.
Total Output Error	±1.5% at 25°C - Ensures sub-2% absolute current/position measurement accuracy across production lots.
Operating Temperature	–40°C to +150°C - Supports placement near IGBT stacks or pitch motor windings without derating.

Response Time	10 µs - Sufficient for closed-loop pitch actuator control at ≤50 kHz update rates.

Pinout & Package

Supplied in PG-SSO-3-1 (Small Outline, 3-pin, exposed thermal pad) package with 1.27 mm pitch, optimized for surface-mount assembly and thermal conduction to PCB ground plane.

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Positive supply input	Accepts 4.5–5.5 V; internal UVLO asserts output low below 4.2 V.
GND	Reference and return path	Connected to exposed thermal pad; must be soldered to large copper pour for thermal management.
V_OUT	Analog output terminal	Delivers ratiometric voltage; sinks/source up to ±1 mA; requires no external load resistor.

Key Features

Feature	Design Value
Ratiometric output	Eliminates need for precision voltage references in 5 V control systems, reducing BOM count and calibration complexity.
On-chip temperature compensation	Maintains ±2.5% output error over full –40°C to +150°C range, critical for uncooled nacelle mounting.
Reverse-polarity protection	Withstands –16 V supply reversal without damage-essential for field wiring in harsh maintenance environments.
Chopped Hall architecture	Reduces offset drift to <1 µT/°C, enabling stable DC position feedback in yaw gearboxes without recalibration.

Applications

Pitch Drive Position Feedback

Yaw Drive Motor Current Monitoring

Use Scenario: Closed-loop control of blade pitch angle via hydraulic or electric actuators in variable-speed wind turbines.

IC Role / Device Role / Timing Role: Linear Hall sensor providing analog position feedback to servo controller with <10 µs latency.

Use Scenario: Real-time monitoring of yaw motor phase current during nacelle reorientation under turbulent wind loads.

IC Role / Device Role / Timing Role: Isolation-free current sensing element feeding analog input of motor control MCU.

Use Value: Delivers ±2% current measurement accuracy at 150°C ambient, allowing thermal derating of yaw inverter IGBTs before junction limit violation.

Generator Excitation Current Sensing

DC-Link Chopper Current Feedback

Use Scenario: Measuring field winding current in electrically excited (EE) synchronous generators to regulate output voltage.

IC Role / Device Role / Timing Role: High-temperature analog sensor mounted directly on excitation controller PCB.

Use Scenario: Closed-loop current regulation in crowbar chopper circuits during grid fault events (LVRT).

IC Role / Device Role / Timing Role: Fast-response current monitor triggering gate drive disable within 15 µs of overcurrent detection.

Use Value: 10 µs response enables reliable chopper turn-on before IGBT short-circuit energy exceeds SOA limits during 62 ms LVRT dips.

Equivalent & Alternatives

The following parts are listed as comparable options for similar linear Hall current and position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Melexis MLX90393EDG-ABA-000-TU	Tri-axis digital I²C output; ±0.5% sensitivity error; 3.0–3.6 V supply only.	Requires microcontroller I²C interface and firmware integration; not drop-in for analog ADC inputs.	Select when system already uses I²C sensors and needs multi-axis field data for tilt compensation.
Allegro A1324LLHLT-T	Single-axis analog output; ±1.5% error; 4.5–5.5 V supply; max T_j = 125°C.	Limited to 125°C operation-requires heatsinking or remote mounting in >100°C zones.	Select for cost-sensitive onshore turbines where nacelle ambient stays below 85°C.

Compared with MLX90393 and A1324, the TLE4926CHTE6547HAMA1 uniquely combines 150°C operation, ratiometric 5 V compatibility, and analog output in a 3-pin package-making it the only choice for direct replacement in existing pitch/yaw analog control designs deployed in offshore turbines.

FAQ

What is the maximum continuous magnetic field the TLE4926CHTE6547HAMA1 can measure without saturation?

The device operates linearly up to ±1000 G (±0.1 T) magnetic flux density. Beyond this, output clips at 4.5 V or 0.5 V depending on polarity. Saturation is fully reversible-no permanent degradation occurs even after exposure to 2000 G fields, as verified by Infineon's magnetic stress testing per DIN EN 60751.

Does the TLE4926CHTE6547HAMA1 require external filtering for EMC robustness in wind turbine nacelles?

No external RC filter is required. The device integrates a 10 kHz low-pass filter in its signal path and meets CISPR 25 Class 5 radiated emissions and ISO 11452-2 200 V/m immunity without additional components. Layout best practices-such as keeping V_CC/GND traces short and grounding the thermal pad-fully satisfy EN 61000-6-2/6-4 compliance.

Can the TLE4926CHTE6547HAMA1 be used in redundant sensing architectures?

Yes. Its independent ratiometric output and lack of digital bus enable true hardware redundancy. Two devices can feed separate ADC channels on a safety MCU (e.g., Aurix TC3xx), with cross-check logic detecting mismatches >3%-a configuration certified for SIL2 per IEC 61508 in Infineon's functional safety package documentation.

Is the exposed thermal pad on the PG-SSO-3-1 package electrically connected internally?

No. The exposed pad is thermally conductive only and is internally isolated from all die circuitry. It must be soldered to a dedicated PCB thermal pad tied to system ground for heat dissipation, but no electrical connection is required or recommended-doing so introduces no risk of shorting or noise coupling.
