onsemi NCV7462 System Basis Chip

onsemi NCV7462 System Basis Chip comes with LIN, CAN, high-side (HS), and low-side (LS) drivers. onsemi NCV7462 chip incorporates an enhanced feature set useful in automotive body control systems. This IC features two 5V voltage regulators, high-side and low-side switches to control LEDs and relays, and supervision functionality like a window watchdog. The NV7462 chip is a highly integrated solution that replaces the external discrete components while maintaining the system's flexibility. Typical applications include de-centralized door electronic systems, body control units (BCUs), and climate control systems.
