Q & A
- What is the primary function of the NCV7344AD10R2G?
The NCV7344AD10R2G serves as the interface between a CAN protocol controller and the physical bus, enabling communication in CAN and CAN FD networks.
- What are the key specifications for the power supply voltage (VCC)?
The power supply voltage (VCC) ranges from 4.75 V to 5.25 V.
- How does the standby mode work in the NCV7344AD10R2G?
In standby mode, both the transmitter and receiver are disabled, and a very low-power differential receiver monitors the bus lines for CAN bus activity. The bus lines are biased to ground, and supply current is reduced to a minimum, typically 10 μA.
- What is the significance of the VIO pin in the NCV7344-3 version?
The VIO pin in the NCV7344-3 version allows direct interfacing with 3 V to 5 V microcontrollers.
- How robust is the NCV7344AD10R2G against ESD pulses?
The NCV7344AD10R2G has very high ESD robustness of bus pins, capable of withstanding >8 kV system ESD pulses.
