NCV7381DP0G

The NCV7381DP0G is an integrated IC, which combines driver and receiver circuits for RS-485 communication capability. It is designed for easy implementation of two or four-wire full-duplex, half-duplex and baud rate from 19.2 Kbps to 100 Kbps. This IC is a great choice for applications requiring extended operation temperature range (e.g. -40°C to +85°C).

Applications for NCV7381DP0G include any medical and industrial communication job that has to operate in a limited physical space, as it can be very easily implemented as a System-On-Chip (SoC) solution, reducing the cost and complexity of the system software. Its capabilities are used in different systems such as Programmable Logic Controller (PLC), Automatic Meter Reading (AMR), automatic test systems, advanced microcontrollers, communication interface communication and especially in the field of automotive systems.

The NCV7381DP0G utilizes a state-of-the-art logic design to improve the output noise margin and reduce electromagnetic interference (EMI) susceptibility. It is also equipped with an on-chip voltage translator which allows monitoring of two or four channels of RS-485 signals from as far away as 65 feet from the data-bus. The integrated driver and receivers meet a typical short circuit fault protection for up to ±20V transients.

The working principle of NCV7381DP0G is based on differential signaling. It uses two wires (one transmit and one receive) to transfer data in full-duplex configuration. The transmit wire can be connected either to the voltage source or ground, depending on the logic level of the data being sent. The receiver is configured to sense digital switches and works by comparing the voltage on both wires. If the voltage from the transmitter is higher than the voltage on the receive wire, then the receiver interprets this as a data bit “1”. Similarly, if the voltage from the transmitter is lower than the voltage on the receiver wire, then the receiver will interpret this as “0”. The NCV7381DP0G also provides a Fault Detect function to ensure that the nodes on the network are communicating correctly. This function monitors the data being transmitted from the transmitter to the receiver, and if there is an error, it will detect it and send a fault signal. This allows the system to alert the user in case of any communication errors.

The NCV7381DP0G is a versatile IC and can be used in any application where differential signaling is required. Its advanced chipset and extended operating temperature range make it a perfect choice for tough automotive and industrial applications. With its built-in Fault Detect function, it ensures reliable data transmission even in harsh conditions.
