Q & A
- What is the primary function of the NCV7357D10R2G?
The NCV7357D10R2G serves as the interface between a CAN protocol controller and the physical bus, providing differential transmit and receive capabilities.
- What is the maximum data rate supported by the NCV7357D10R2G?
The NCV7357D10R2G supports data rates up to 5 Mbps.
- What is the purpose of the VIO pin on the NCV7357-3 version?
The VIO pin is used for digital signal logic level adaptation, allowing proper adjustment of I/O levels between the microcontroller and the transceiver.
- What protection features does the NCV7357D10R2G have?
The device includes thermal protection, bus pins short circuit proof to supply voltage and ground, and protection against automotive electrical transients (ISO 7637).
- What is the TxD Dominant Timeout Function?
This function prevents the bus lines from being driven to a permanent dominant state by disabling the transmitter if the TxD pin is forced permanently low, ensuring a minimum possible bit rate of 17 kbps.
- What is the silent mode of the NCV7357D10R2G?
In silent mode, the transmitter is disabled, and the bus pins are in a recessive state, allowing the transceiver to listen to the bus but preventing the controller from sending data.
- Is the NCV7357D10R2G qualified for automotive use?
Yes, the NCV7357D10R2G is AEC-Q100 Grade 0 qualified and PPAP capable.
- What is the package type of the NCV7357D10R2G?
The NCV7357D10R2G is available in an SOIC-8 package.
- How does the NCV7357D10R2G manage electromagnetic emissions?
The device is designed to have low Electromagnetic Emission (EME) and high Electromagnetic Immunity, even without a common-mode choke.
- What happens to the device during an undervoltage condition?
During an undervoltage condition on VCC or VIO, the device enters a power-off mode, resetting the internal logic and disabling the transceiver. The bus pins are kept floating until the supply voltages recover.
