FINEST Integrates Melexis Current Sensors in High-Performance Inverters for Next-Gen EV Platforms

­Melexis current sensor ICs have been selected for use in traction inverter systems developed by FINEST, a leading global high-tech company specializing in automotive transmission and electric drive systems. FINEST, a key supplier to premium automotive OEMs worldwide, selected the IMC-Hall® technology, reinforcing Melexis’ role in delivering precise current measurement for motor control, efficiency, and system safety. 

As a pioneering technical partner to global automotive OEMs, FINEST provides high-performance traction inverters that are essential for the next generation of electrified vehicles. With inverter performance directly influencing how efficiently battery power is delivered to the motor, accurate current sensing is fundamental to minimizing energy losses, limiting heat generation and maintaining consistent motor control. In real-world operating conditions, these benefits help maximize the use of available battery energy, supporting greater EV range and helping OEMs meet driver expectations for everyday usability.

Safety and Efficiency Drive Sensor Selection

As EV inverter platforms move into higher-volume production, current sensing has to support more than accurate measurement alone. It must help manufacturers deliver efficient powertrain performance, stable motor control and long-term reliability in vehicles that drivers depend on every day.

For FINEST, this means selecting sensing technologies that can balance cost, integration and robust performance across real operating conditions, including temperature variation, electrical noise and full vehicle lifetime requirements. Melexis’ conventional Hall and IMC-Hall® technologies support this balance, helping FINEST maintain dependable inverter performance at scale while contributing to efficient power delivery, reduced energy losses and a consistent driving experience for end users.

Enabling Integration Without Compromising Performance

The shift from module-based current sensing to direct integration on inverter control boards is accelerating across the industry, as designers look to reduce system cost, footprint and complexity. By integrating Melexis current sensors, inverter designers can simplify their architectures while maintaining robust measurement performance in demanding operating conditions.

Melexis current sensors are engineered to withstand the effects of electrical noise, thermal drift and mechanical stress, helping designers avoid the compromises often associated with more compact integration. Combined with close technical support from Melexis engineering teams, this enables efficient implementation and system-level optimization across high-volume inverter platforms.
