ON Semiconductor NCV7428D13R2G System Basis Chip

The NCV7428D13R2G from ON Semiconductor is a versatile System Basis Chip (SBC) designed to support the networking applications of automotive control units. It is an integral component for in-vehicle networks, providing the necessary interfaces for power management, communication, and diagnostics in a single package. This chip is part of ON Semiconductor's high-performance automotive product lineup, which is known for its reliability and robustness, meeting the stringent requirements of the automotive industry.

The NCV7428D13R2G integrates a CAN transceiver that complies with the ISO11898-2 standard, ensuring reliable communication within the Controller Area Network (CAN). This allows for high-speed data transmission and error-resistant communication between the various electronic control units (ECUs) within a vehicle. The transceiver's dominant time-out function prevents the bus from being driven indefinitely in the dominant state, enhancing the safety and reliability of the network.

In addition to the CAN interface, the NCV7428D13R2G offers a range of power management features. It includes a 5V/100mA voltage regulator with various protection mechanisms, such as overcurrent protection, overtemperature shutdown, and under-voltage lockout. These features ensure a stable power supply for the connected microcontroller and other peripherals, even in the challenging conditions of the automotive environment.

The device also boasts a low-power mode with a wake-up capability, which is essential for reducing the overall power consumption of the vehicle when it is not in operation. This helps in meeting the increasingly stringent automotive standards for energy efficiency and battery management.

For diagnostics and system monitoring, the NCV7428D13R2G is equipped with a watchdog timer that supervises the correct operation of the microcontroller. The watchdog timer can reset the microcontroller in case of a malfunction, thereby increasing the system's reliability.

Manufactured in a compact 14-SOIC package, the NCV7428D13R2G is designed to withstand the harsh conditions of automotive applications, including extended temperature ranges and high levels of electromagnetic interference (EMI). It is an ideal solution for automotive engineers looking to enhance the performance, safety, and efficiency of their in-vehicle network systems.
