Texas Instruments says its isolated Controller Area Network (CAN) flexible data rate (FD) transceivers combine the industry's highest bus fault protection, highest common-mode transient immunity (CMTI), and lowest electromagnetic emissions into a 35% smaller package. With a higher working voltage than comparable devices and faster communication speeds than the classic CAN standard, the ISO1042 and ISO1042-Q1 reliably protect low-voltage circuits and increase communication throughput in industrial applications such as grid infrastructure, motor drives and building automation, and hybrid electric vehicles and electric vehicles (HEVs/EVs). For more information, see www.ti.com/iso1042-pr and www.ti.com/iso1042-Q1-pr.
Shared features include:
- Highest working voltage: With an 18 percent higher working voltage of 1,000 Vrms and a withstand voltage of 5,000 Vrms, the ISO1042 andISO1042-Q1 feature longer lifetimes, resulting in improved system reliability.
- Increased device protection: Featuring a high bus fault protection of ±70 V, which provides a 20 percent higher short-to-DC margin, the ISO1042and 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-Q1feature 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 Mb/s 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 in either a 16-pin 10.3 mm x 7.5 mm or an eight-pin 5.8 mm x 7.5-mm small-outline integrated (SOIC) package. Pricing starts at $1.69 each/1,000 for industrial versions and $1.99 each/1,000 for automotive versions. In addition, ISO1042DWEVM and ISO1042DWVEVM evaluation modules are available for $49 each.
