Do you believe increasing complexity in electric vehicle technology will make future repairs more expensive?
Melexis has expanded its sensor portfolio with the release of the MLX91224 and MLX91225 current sensors. These new devices are designed to support high-voltage requirements in both automotive and industrial sectors.
Why it matters
As high-voltage systems become more prevalent in industrial and automotive designs, manufacturers require compact, integrated components capable of maintaining functional safety standards. These sensors provide an all-in-one solution that combines sensing, conditioning, and isolation to meet modern energy infrastructure needs.
The DH package supports measurement currents up to 100 ARMS and surge currents of ±29 kA. The MLX91224 is designed for 5 V systems, while the MLX91225 supports 3.3 V systems, with both operating between -40 °C and 150 °C.
The players
Melexis
Melexis is a global engineering company that designs and manufactures semiconductor solutions for the automotive and industrial sectors.
The details
The devices function by passing current through an internal lead frame, which allows Hall plates to differentially sense the generated magnetic flux. This design integrates the current conductor, sensing element, signal conditioning, and isolation into a single package to simplify integration.
Timeline
Melexis announced the sensor portfolio expansion on September 22, 2026.
The Tech Race
This release reflects the broader industry shift toward compact, high-isolation sensors that replace traditional, bulkier discrete current-sensing components. These advancements allow manufacturers to compete in the high-voltage market by integrating critical safety features directly into the silicon.
Engineers and product designers can expect reduced footprint requirements on circuit boards due to the integration of sensing and isolation in a single package. These sensors streamline the development of high-voltage systems, potentially accelerating the rollout of more efficient electric-powered devices.
The takeaway
The move underscores the growing importance of safety-rated, high-voltage components in modern system design. Designers should prioritize evaluating these integrated packages to reduce physical space constraints while maintaining compliance with stringent safety standards.
