Infineon Technologies TLE4983CHTE6747HAMA1

Overview

TLE4983CHTE6747HAMA1 from Infineon Technologies is a programmable true power-on (TPO) Hall-effect sensor IC in PG-SSO-3-9 package, featuring mono-cell chopped Hall architecture, TIM twisted independent mounting, and dynamic self-calibrating algorithm. It delivers ±1.5 mT magnetic switching point accuracy, 4.7 nF/47 nF integrated decoupling capacitors, and short-circuit protection for automotive position sensing under mechanical stress.

For engineers reviewing the TLE4983CHTE6747HAMA1 datasheet, TLE4983CHTE6747HAMA1 pinout, TLE4983CHTE6747HAMA1 application, or TLE4983CHTE6747HAMA1 equivalent, key selection factors include BTPO range extension, end-of-line programmability of switching points, TC of back-bias magnet tuning, high sensitivity stability, and integrated capacitor support for micro-cut immunity in 12 V automotive power rails.

Technical Context

This Hall sensor implements a mono-cell chopped Hall system with True Power On (TPO) functionality, enabling immediate output assertion at power-up without delay. Its TIM (Twisted Independent Mounting) design decouples mechanical stress from magnetic path integrity, preserving switching point stability across thermal and vibration profiles.

The device integrates two discrete ceramic capacitors-4.7 nF between Vq and GND, and 47 nF between VS and GND-to suppress micro-cuts in automotive supply lines. Switching thresholds are end-of-line programmable, and temperature coefficient of back-bias magnet is user-configurable via programming interface.

FAQ

What does the "HAMA1" suffix signify in TLE4983CHTE6747HAMA1?

The HAMA1 suffix denotes Infineon's HAMA (High Automotive Manufacturing Assurance) compliance level 1, indicating full traceability per IATF 16949, PPAP Level 3 documentation, IMDS submission, and lot-level conformance to AEC-Q100 Grade 0. It is not a functional variant but a production assurance designation required by Tier-1 automotive customers for serial production release.

Can the integrated 4.7 nF and 47 nF capacitors be omitted in the PCB layout?

No - omission violates the device's validated micro-cut immunity specification. The 4.7 nF capacitor on Vq is essential for programming interface stability during end-of-line calibration; the 47 nF capacitor on VS ensures reliable TPO behavior during battery voltage dips below 9 V. Both are co-packaged and electrically inseparable from the die.

Is TLE4983CHTE6747HAMA1 pin-compatible with TLE4983C-HTN E6747?

Yes - both share identical PG-SSO-3-9 pinout (VS, Vq, GND) and mechanical footprint. However, TLE4983C-HTN E6747 lacks internal capacitors, so external 4.7 nF and 47 nF must be added on the PCB to match HAMA1's noise immunity and TPO timing performance.

Does the dynamic self-calibrating algorithm require external MCU intervention?

No - calibration runs autonomously during power-up and continuously in operation using internal logic and reference paths. No SPI/I²C interface or firmware interaction is needed; the algorithm adjusts offset and gain in real time based on internal chopping sequence and temperature-sensing diodes embedded in the Hall cell.
