Texas Instruments (TI) today introduced two new isolated Controller Area Network (CAN) flexible data rate (FD) transceivers that combine the industry's highest bus fault protection, highest common-mode transient immunity (CMTI), and lowest electromagnetic emissions into a 35 percent smaller package.
With a higher working voltage than competing devices and faster communication speeds than the classic CAN standard, the ISO1042 and ISO1042-Q1 help engineers better protect low-voltage circuits and increase communication throughput in industrial applications such as grid infrastructure, motor drives and building automation, as well as hybrid electric vehicles and electric vehicles (HEVs/EVs).
Key features and benefits of TI's ISO1042 and ISO1042-Q1 isolated CAN FD transceivers include:
Highest working voltage: With an 18 percent higher working voltage of 1,000Vrms and a withstand voltage of 5,000Vrms, the ISO1042 and ISO1042-Q1 feature longer lifetimes, resulting in improved system reliability.
Increased device protection: Featuring a high bus fault protection of ±70V, which provides a 20 percent higher short-to-dc margin, the ISO1042 and ISO1042-Q1 protect 12-, 24- and 48-V battery or power-supply systems during high-voltage shorts.
Industry-leading immunity and emissions:
- Highest electromagnetic immunity: The ISO1042 and ISO1042-Q1 feature a CMTI of 85 kV/us (minimum) with high ESD protection of +/- 8 kV, using the International Electrotechnical Commission (IEC) testing standard, which helps engineers design electronics that can maintain operation in noisy environments.
- Lowest EMC emissions: The ISO1042 and ISO1042-Q1 deliver the industry's lowest electromagnetic compatibility (EMC) emissions, thereby maintaining system signal integrity. The ISO1042-Q1 meets the automotive industry standard (IEC TS62228) for robust EMC.
Drive signals faster in CAN-based systems: These transceivers support CAN FD speeds up to 5 Mbps with a short loop delay of 215 ns (maximum), enabling faster payload compared to classic CAN.
Package, availability and pricing
The ISO1042 and ISO1042-Q1 are available now through the TI store and authorized distributors. Basic and reinforced options of each device are available in either a 10.3-mm-by-7.5-mm, 16-pin or a 5.8-mm-by-7.5-mm, 8-pin small-outline integrated (SOIC) package. Pricing starts at US$1.69 in 1,000-unit quantities for industrial versions and US$1.99 in 1,000-unit qualities for automotive versions.
