Optimized for modern vehicle systems, low power operation, selective wake-up support, and high-speed communication up to 5 Mbps — ideal for infotainment, powertrain, and body electronics applications.
NOVOSENSE Microelectronics has released the NCA1145B, a high-performance, automotive-grade CAN transceiver designed to interface seamlessly between a CAN protocol controller and the physical two-wire CAN bus. Engineered to meet the demands of modern automotive systems, it complies fully with the ISO11898-2:2024 standard and is AEC-Q100 Grade 1 qualified, ensuring robust performance in harsh automotive environments.
It has ultra-low power consumption in both Standby and Sleep modes, making it ideal for systems where energy efficiency is critical. The transceiver also supports CAN Partial Networking through a selective wake-up function, allowing it to detect ISO-compliant wake-up frames or standard CAN wake patterns. Additionally, a WAKE pin enables local wake-up, ensuring flexible and reliable system activation.
The key features are:
- Low-current Standby and Sleep modes
- Autonomous bus biasing
- Remote wake-up via CAN or selective wake-up frame; local via WAKE pin
- Overtemperature warning & shutdown
- Configurable via 16/24/32-bit SPI
- Data rate up to 5 Mbps
- Advanced system/transceiver interrupt handling
It supports I/O voltage ranges of 1.8V, 3.3V, and 5V, allowing easy integration with a variety of microcontrollers. It features a wide operating voltage range with VCC from 4.5V to 5.5V, VIO from 1.7V to 5.5V, and VBAT from 4.5V to 40V. Built-in bus fault protection from -58V to +58V enhances reliability, while overtemperature warning and shutdown mechanisms provide additional safeguards.
With support for SPI communication interfaces (16-, 24-, or 32-bit), the transceiver allows flexible configuration, monitoring, and diagnostics. It also offers autonomous bus biasing, advanced interrupt handling, and operates at data rates up to 5 Mbps, making it suitable for high-speed communication demands.
Applications include automotive infotainment systems, instrument clusters, hybrid and electric vehicle systems, powertrain systems, as well as body electronics and lighting systems. Designed for use in challenging automotive environments, it operates over a temperature range of -40°C to +125°C and is available in RoHS and REACH-compliant SOP14 and DFN14 packages.
