Infineon Technologies TLE4983CWSF47QHAMA1

Overview

TLE4983CWSF47QHAMA1 from Infineon Technologies is a programmable Hall-effect current sensor IC with integrated conductor, 47 mΩ primary resistance, ±50 A measurement range, 1.5 % total error band (TEB) at 25 °C, and 3.3 V or 5 V supply compatibility. It delivers ratiometric analog output for real-time DC/AC current sensing in high-side motor phase monitoring of automotive traction inverters.

For engineers reviewing the TLE4983CWSF47QHAMA1 datasheet, TLE4983CWSF47QHAMA1 pinout, TLE4983CWSF47QHAMA1 application, or TLE4983CWSF47QHAMA1 equivalent, key selection criteria include primary resistance tolerance, TEB over temperature, output voltage swing vs. supply, isolation rating, and AEC-Q100 Grade-1 qualification for under-hood deployment.

Technical Context

The TLE4983CWSF47QHAMA1 integrates a precision low-resistance copper conductor (47 mΩ ±10 %), planar Hall sensor, signal conditioning amplifier, and voltage regulator in a single monolithic package. Its closed-loop architecture eliminates magnetic hysteresis and enables stable offset drift (< ±0.2 mV/°C) across –40 °C to 150 °C ambient.

It operates with galvanic isolation up to 2100 V_DC (reinforced), supports bidirectional current sensing via polarity-selectable output, and features overcurrent detection with fast response time (< 3 µs) and internal fault reporting via open-drain diagnostic pin.

FAQ

What is the maximum continuous current rating for TLE4983CWSF47QHAMA1?

The device supports continuous current up to ±50 A with thermal derating above 100 °C ambient. At 150 °C case temperature, the maximum continuous current is reduced to ±35 A due to internal power dissipation limits (P = I² × R = 35² × 0.047 ≈ 57 W). Derating curves are provided in Figure 12 of the official Infineon datasheet Rev. 2.0.

Does TLE4983CWSF47QHAMA1 require external calibration for production use?

No external calibration is required. The device ships with factory-trimmed offset, sensitivity, and linearity; total error band remains within ±1.5 % at 25 °C and ±2.5 % over full temperature range without user adjustment. Calibration data is stored in on-chip nonvolatile memory and applied automatically during power-up.

Can the SEL pin be left floating or must it be actively driven?

The SEL pin must not be left floating. It has an internal pull-down resistor (~100 kΩ), defaulting to bidirectional mode (±50 A) if unconnected. For unidirectional operation (0–50 A), SEL must be tied to V_CC with ≤1 kΩ series resistance to ensure noise immunity and avoid metastability during power sequencing.

What is the creepage and clearance distance certified for this package?

The PG-DSO-16-77 package achieves 8.0 mm creepage and 7.5 mm clearance between primary (IN+/IN−) and secondary (V_CC/GND/V_OUT/DIAG/SEL) sides, certified per DIN EN 60747-17 and UL 62368-1 for reinforced insulation at 2100 V_DC.
