Engineers can simplify high-temperature automotive designs while helping improve signal isolation and in-vehicle network performance with TI’s new Grade 0 devices.

They are qualified to the Grade 0 ambient operating temperature specification of the 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.

This 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 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.
