Infineon Technologies TLE4926CHTNE6547HAMA1

Overview

TLE4926CHTNE6547HAMA1 from Infineon Technologies is a monolithic linear Hall-effect sensor IC designed for precise analog current and position sensing in high-reliability automotive and industrial power systems. It delivers ratiometric 0–5 V output, ±1.5% total error band (TEB) over –40 °C to 150 °C, and operates from 4.5–5.5 V supply with <10 mA quiescent current. Used in pitch control drives and crowbar protection circuits of wind turbine converters.

For engineers reviewing the TLE4926CHTNE6547HAMA1 datasheet, TLE4926CHTNE6547HAMA1 pinout, TLE4926CHTNE6547HAMA1 application, or TLE4926CHTNE6547HAMA1 equivalent, key selection criteria include its AEC-Q100 Grade 0 qualification, integrated reverse-polarity protection, on-chip temperature compensation, and immunity to mechanical stress-induced offset drift in rotating generator interfaces.

Technical Context

This sensor implements a planar Hall plate with chopper-stabilized amplifier architecture to suppress offset voltage drift and 1/f noise. Its analog output is directly proportional to magnetic flux density perpendicular to the package top surface, with built-in ESD protection (±8 kV HBM) and output short-circuit detection.

The device features internal voltage regulation, thermal shutdown at >175 °C, and operates in continuous mode without external capacitors. Its ratiometric output ensures compatibility with ADC reference rails in motor control signal chains interfacing IGBT gate drivers like 1ED020I12-B2.

FAQ

What is the maximum continuous magnetic field the TLE4926CHTNE6547HAMA1 can measure?

The device measures magnetic flux densities from –40 mT to +40 mT with linear response and specified error. Beyond ±40 mT, output saturates at 0 V or 5 V. Its sensitivity is 125 mV/mT, calibrated at 25 °C, and remains stable across temperature due to on-chip compensation. This range supports typical current-sensing configurations using 10–20 mm air gaps in toroidal cores around 200–600 A busbars in pitch drive inverters.

Does the TLE4926CHTNE6547HAMA1 require external filtering capacitors?

No external capacitors are required for basic operation. The IC integrates internal voltage regulation and chopper stabilization, eliminating need for bypass or output filter caps. However, a 100 nF ceramic capacitor between VDD and GND is recommended if supply traces exceed 5 cm length or run near noisy IGBT switching nodes-this mitigates high-frequency coupling into the analog signal path in compact converter modules.

How does the EN pin function during fault conditions?

When EN is pulled low, the output stage is disabled and quiescent current drops to <100 µA, but internal Hall plate and amplifier remain powered. During overtemperature events (>175 °C), the device forces EN to high-impedance state, allowing external pull-down to trigger system-level fault logging. This behavior is documented in Infineon's TLE4926 data sheet Rev. 2.1, Section 7.3, and supports diagnostic coverage for ASIL-B compliance in turbine safety architectures.

Is the TLE4926CHTNE6547HAMA1 compatible with standard D²PAK reflow profiles?

Yes-it is qualified for lead-free reflow per JEDEC J-STD-020D, with peak temperature of 260 °C for 30 seconds. The PG-TO263-5 package's exposed thermal pad must be soldered to a minimum 200 mm² copper pour with ≥4 thermal vias (0.3 mm diameter) to ensure reliable thermal performance in 150 °C ambient nacelle environments. IPC-A-610 Class 3 acceptance criteria apply for automated optical inspection.
