The ISL8490IB-T is an integrated driver-receiver and transceiver which provides a direct connection between two nodes on a Local Interconnect Network (LIN) bus. It allows for data to be transmitted and received in a single integrated device. The ISL8490IB-T is an advanced solution for the entire LIN bus data transmission needs, from low power transmitter application to the complex node network communication requirements.

The ISL8490IB-T is designed for use in systems with One-Wire networks and bi-directional LIN systems. It provides a single, integrated solution for basic one- and two-wire serial communication. It is also equipped with an active galvanic-isolation and ESD protection, allowing it to be integrated in any LIN bus system without the need of additional isolation components.

The ISL8490IB-T is primarily used to enable communication between modules located in a LIN system. It can be easily integrated into any system because it operates using the same protocol and data formats as standard LIN transceivers. This makes it an ideal choice for space constrained applications. It also includes active isolation circuitry to protect both the transceiver device and the connected network.

The ISL8490IB-T features a built-in transceiver that is capable of switching between two modes: TX (Transmit) and RX (Receive). In TX mode, the transceiver can send out data frames on the LIN bus according to the LIN protocol. In RX mode, the transceiver can receive data frames from the LIN bus and transfer them to the program memory.

The ISL8490IB-T has an embedded LIN data frame controller that can handle data frames from the host system as well as from the LIN bus. The data frame controller can check for errors in the data frame and can also perform certain transceiver actions such as transmitting data frames and receiving them.

In addition to its transceiver capabilities, the ISL8490IB-T features an integrated hardware watchdog timer. The hardware watchdog timer is used to monitor the health of the system by regularly sending out a heartbeat signal. If the heartbeat signal is not received within a certain window of time, the transceiver will reset itself and will attempt to reestablish communication between the nodes.

The ISL8490IB-T also includes built-in safety features to help prevent interference with other devices. It includes measures such as noise reduction, glitch filtering, and power sequencing, which are designed to ensure that the LIN messages are streamed from one node to another without error.

In summary, the ISL8490IB-T is an advanced driver-receiver and transceiver designed for use in systems with One-Wire networks and bi-directional LIN systems. It provides a direct connection between two nodes on a LIN bus, allows for data exchange in both directions, and has built-in safety features to prevent interference with other devices. Its advanced features make it an ideal choice for space-constrained applications, and its easy-to-integrate design make it a perfect solution for any LIN bus system.
