Redefining Hall-based current sensing precision
Truflux
Melexis TruFlux™ technology overcomes traditional current sensing trade-offs in EV and BESS applications. By running on-chip hysteresis compensation on the MLX91230, it achieves Fluxgate-level precision at low cost.
Top features
- High Accuracy: < ±0.2% room-temperature accuracy (< ±0.5% over full temperature range)
- Low Offset Drift: < 50 mA offset drift for precise low-current measurement
- Intrinsic Galvanic Isolation: Safe, isolated current measurement without requiring external isolation amplifiers.
- Low System Cost & Compact Footprint: Enables inexpensive SiFe laminated cores while outperforming bulky, expensive Fluxgate alternatives.
- Simplified Integration: Automates magnetic parameter extraction during development and uses quick EoL fine-tune calibration in production.

Product description
What is TruFlux™?
TruFlux™ is an innovative algorithm and calibration approach running on Melexis Hall-effect sensor ICs (such as the MLX91230). It eliminates the inherent hysteresis and non-linearity of low-cost ferromagnetic cores, unlocking ultra-high-precision current sensing for demanding battery management applications.
Simple integration
Beyond on-chip algorithms, TruFlux™ automates parameter extraction from a single core characterization during development, eliminating the need for deep magnetics expertise.
