ISO1042BQDWRQ1 Automotive-Grade Isolated CAN Transceiver

The ISO1042BQDWRQ1 from Texas Instruments is a high-performance, automotive-grade isolated Controller Area Network (CAN) transceiver that meets the stringent requirements of in-vehicle networks. This robust component is designed to provide reliable communication in harsh environments, making it an ideal choice for automotive applications such as powertrain, chassis, and advanced driver assistance systems (ADAS).

Featuring galvanic isolation of 5000 VRMS for 1 minute per UL 1577, the ISO1042BQDWRQ1 ensures protection against high voltage and prevents noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. With its industry-leading electromagnetic compatibility (EMC), this transceiver is resistant to electrical disturbances that can occur in the automotive setting.

The device supports up to 5 Mbps data rates with CAN FD and is compatible with both the ISO 11898-2:2016 and ISO 11898-5:2007 standards. It assures a signaling rate up to 2 Mbps in the classic CAN and 5 Mbps in the CAN FD. The ISO1042BQDWRQ1 has an extended common-mode range of -12 V to +12 V, which exceeds the traditional CAN common-mode range, ensuring increased reliability in electrically noisy environments.

Additionally, the ISO1042BQDWRQ1 offers a bus fault protection of ±70 V, enhancing the device's resilience to faults and ensuring the protection of network communication against disruptions. The device is characterized for operation over the ambient temperature range of -40°C to +125°C, suitable for the demanding conditions of automotive applications.

The transceiver comes in a compact SOIC-16 DW package, making it easy to integrate into space-constrained applications. It also includes features such as thermal shutdown, UVLO (Under Voltage Lock Out), and over-current protection, which contribute to its overall reliability and longevity in the field.

In summary, the ISO1042BQDWRQ1 is a cutting-edge solution for automotive systems requiring high-speed data transmission with robust isolation and protection features, ensuring safe and reliable operation in challenging environments.
