System Basis Chip with a High-Speed CAN/CAN FD, Two LINs and a Boost-Buck DC/DC Converter.

NCV7471B/C is a System Basis Chip (SBC) integrating functions typically found in automotive Electronic Control Units (ECUs) in the body domain. NCV7471B/C provides and monitors the low−voltage power supplies for the application microcontroller and other loads, monitors the application software via a watchdog and includes high−speed CAN/CANFD and LIN transceivers allowing the ECU tohost multiple communication nodes or to act as a gateway unit. The on−chip state controller ensures safe power−up sequence and supports low−power modes with a configurable set of features including wakeup from the communication buses or by a local digital signal WU. The status of several NCV7471B/C internal blocks can be read by the microcontroller through the serial peripheral interface or can beused to generate an interrupt request.
