System Basis Chip with CAN, LIN, HS & LS Drivers NCV7462 The NCV7462 is a monolithic LIN/CAN SystemBasisChip with enhanced feature set useful in Automotive Body Control systems. Besides the bus interfaces the IC features two 5 V voltage regulators, www.onsemi.com highside and lowside switches to control LEDs and relays, and supervision functionality like a window watchdog. This allows a highly integrated solution by replacing external discrete components while maintaining the system flexibility. As a consequence, the board space and ECU weight can be minimized.
