Overview
The NCV7344AD13R2G is a high-speed, low-power CAN (Controller Area Network) and CAN FD (Flexible Data Rate) transceiver produced by onsemi. This component serves as the interface between a CAN protocol controller and the physical bus, enabling robust communication in various network environments. It is designed to support data rates beyond 1 Mbps, making it suitable for HS-CAN networks and applications requiring low-power modes with wake-up capability via the CAN bus.

Q & A
- What is the primary function of the NCV7344AD13R2G?
The NCV7344AD13R2G is a CAN and CAN FD transceiver that acts as the interface between a CAN protocol controller and the physical bus.
- What are the supported data rates for the NCV7344AD13R2G?
The component supports data rates beyond 1 Mbps, including CAN FD requirements.
- What are the operating modes of the NCV7344AD13R2G?
The component has two operating modes: Normal Mode and Standby Mode, selectable via the STB pin.
- What is the power supply voltage range for the VCC pin?
The power supply voltage range for the VCC pin is 4.75 V to 5.25 V.
- How does the standby mode function in the NCV7344AD13R2G?
