NCV7462中文资料System Basis Chip with LIN, HS CAN, Two LDO, and HS/LS Drivers数据手册ONSEMI规格书

描述 Description

The NCV7462 is a monolotic LIN/CAN System-Basis-Chip with enhanced feature set usefull in Automotive Body Control systems. Besides the bus interfaces the IC features two 5V 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.
