The NCV7429 is a monolithic LIN System-Basis-Chip with enhanced feature set useful in Automotive Body Control systems. Besides the LIN bus interface the IC features a 5 V voltage regulator, high-side and low-side 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.
