New automotive grade digital isolator range for NEVs launched

NOVOSENSE Microelectronics has released a new range of third-generation automotive-grade digital isolators. The NSI83xx series of capacitive-based isolators delivers superior EOS resilience and minimal power noise susceptibility, making them excellent for simplified system-level EMI mitigation and ensuring signal integrity in dense, high-frequency SiC-based switching environments.

The series delivers reinforced insulation above 10kVrms, a CMTI of 200kV/μs, and a lifespan exceeding 30 years. Designed especially for applications like BMS and traction inverters, the AEC-Q100-compliant series stands out with industry-leading EMI performance, achieving over 10dB margin in the CISPR 25 Class 5 test.

The company is also introducing its NSI67x0 smart isolated gate driver series to the European market. Built to support the latest SiC and IGBT devices, these drivers provide precise control, robust CMTI, and short propagation delays vital for managing the fast switching speeds and high voltages in modern traction inverter architectures. Their integration helps lower design complexity while improving gate drive reliability under harsh electrical transients.

Also debuting in Europe is the NSM201x-P Hall-effect current sensor series. Tailored for NEV OBCs, DC-DC converters, and solar system applications, these sensors can attain sub-±1% sensitivity error and ultra-low zero offset error across wide temperature ranges, thanks to advanced calibration and compensation technologies. With 5000Vrms isolation, rapid 1.5μs overcurrent detection, and primary-side resistance as low as 0.27mΩ, the NSM201x-P offers exceptional accuracy and safety in space-constrained, high-current environments. Its wide model range and packaging options support flexible integration into unidirectional and bidirectional systems, including Vehicle-to-Grid (V2G) enabled OBCs.
