System Basis Chip with Dual LIN, HS CAN and 500 mA Boost-Buck DC-DC

NCV7471(A) is a System Basis Chip (SBC) integrating functions typically found in automotive Electronic Control Units (ECUs) in the body domain. NCV7471 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 and LIN transceivers allowing the ECU to host 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 NCV7471(A) internal blocks can be read by the microcontroller through the serial peripheral interface or can be used to generate an interrupt request.
