onsemi NCV7462DQ1R2G

The NCV7462 is a monolithic LIN/CAN System−Basis−Chip with enhanced feature set useful in Automotive Body Control systems. Besides the bus interfaces the IC features two 5 V voltage regulators, high−side and low−side switches to control LED’s 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.
