CA-IS2062A

The CA-IS2062A is a galvanically-isolated CAN transceiver with a built-in isolated DC-DC converter, which eliminates the need of an external isolated power supply to save the system space and simplify the design. The internal logic input and output buffer are separated by a silicon oxide (SiO2) insulation barrier that provides up to 2.5-kVRMS (60s) galvanic isolation as well as typical CMTI of ±150kV/µs. The isolation barrier helps to ensure the correct transmission of data by breaking the ground loops and reducing the noise where there are large differences in ground potential between ports.

The CA-IS2062A operates from a single 5V supply VDDP on the logical side, and the logical supply VDDL ranges from 2.5V to 5.5V. VDDL and VDDP could be separated and powered by different voltages, which is convenient to interface with the low-voltage controller. VDDL could also share the same 5V power supply with VDDP. An integrated DC-DC converter generates the 5V output voltage VISOOUT for the bus side to supply the VISOIN which is the power supply pin of CAN transceiver. It needs to connect VISOOUT to VISOIN directly in applications.

The transceiver in CA-IS2062A supports CAN FD up to 5Mbps and features integrated protection for robust communication, including current limiting on bus pins (CANH/CANL), thermal shutdown protection, and up to ±42V bus fault protection voltage. The dominant timeout (DTO) detection prevents bus lockup caused by controller error or by a fault on the TXD input. Furthermore, this device offers up to ±24V input common-mode range (CMR), which far exceeds the ISO 11898-2 specification of –2V to +7V, supporting reliable data communication.

The CA-IS2062A devices are packaged in ultra-compact LGA16 packages, which could save PCB space significantly. This device is specified over the extended industrial temperature range of –40°C to 125°C.
