Industry's first Grade 0 digital isolator enables reliable communication and protection in HEV/EV systems that exceed 125°C

04/14/2020

Texas Instruments (TI) introduced the industry’s first digital isolator that is qualified to the Grade 0 ambient operating temperature specification of the Automotive Electronics Council (AEC)-Q100 standard. The ISO7741E-Q1 features an industry-leading 1.5-kVRMS working voltage and supports temperatures up to the Grade 0 maximum of 150°C. The new isolator enables engineers to better protect low-voltage circuitry from high-voltage events in hybrid electric vehicle (HEV) and electric vehicle (EV) systems and avoid having to design in cooling systems to reduce temperatures to below 125°C – the maximum temperature Grade 1-qualified integrated circuits (ICs) can support.

In addition, when implementing Controller Area Network Flexible Data Rate (CAN FD) communications in system designs, engineers can increase in-vehicle network (IVN) signal protection and reach by using the ISO7741E-Q1 with the new TCAN1044EV-Q1 Grade 0 CAN FD transceiver.
