Smallest reinforced isolated CAN FD

Smallest reinforced isolated CAN FD

Texas Instruments has launched two new isolated CAN flexible data rate (FD) transceivers that feature high bus fault protection and common-mode transient immunity (CMTI) and low electromagnetic emissions.

The transceivers have a higher working voltage than competing devices and faster communication speeds than the classic CAN standard. The ISO1042 and ISO1042-Q1 are intended to protect low-voltage circuits and increase communication throughput in industrial applications.

Key features and benefits of TI’s ISO1042 and ISO1042-Q1 isolated CAN FD transceivers

• 1,000 Vrms working voltage and a withstand voltage of 5,000 Vrms. The ISO1042 and ISO1042-Q1 have longer lifetimes, leading to improved system reliability.
• A high bus fault protection of ±70 V to provide 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:
  ◦ The ISO1042 and ISO1042-Q1 feature a CMTI of 85 kV/us (minimum) with high ESD protection of +/- 8 kV, using the IEC testing standard.
  ◦ The ISO1042 and ISO1042-Q1 deliver the industry’s lowest electromagnetic compatibility (EMC) emissions, maintaining system signal integrity. The ISO1042-Q1 meets the automotive industry standard (IEC TS62228) for robust EMC.

• The 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.
