ISL4270EIR-T is an integrated pre-driver/receiver for N-CAN applications. It supports one CAN transceiver channel and provides a complete pre-driver/receiver including an integrated voltage regulator. The ISL4270EIR-T eliminates the need for external components and improves reliability.

The ISL4270EIR-T is suitable for automotive applications such as safety, body control, airbag, ABS, engine control and other CAN applications. It is also used in industrial and consumer applications requiring reliable CAN communication.

The ISL4270EIR-T features full integration of the physical layer, a low-power operation, a low cost-size-weight solution, a compact footprint, and a wide ambient temperature range. In addition, the ISL4270EIR-T has high EMI immunity and excellent ESD protection.

The ISL4270EIR-T includes the following components:

• A CAN pre-driver with slew-rate control, able to achieve high data rate with low EMI
• A CAN receiver with integral filter and 5V regulator
• A 44-pin TSSOP package

The ISL4270EIR-T supports the N-CAN protocol and provides a low-cost and low-power solution for automotive and industrial applications requiring reliable CAN communication. The device features full integration of the physical layer, a wide ambient temperature range, and excellent EMI immunity. The integrated voltage regulator eliminates the need for any external components, thus reducing cost and improving reliability.

The ISL4270EIR-T supports a variety of operating modes that can be programmed through digital and/or analog signals. These include normal, sleep, standby, and wake-up modes.

The basic operation of the ISL4270EIR-T is as follows:

• The CAN transceiver is in a “sleep” mode, consuming minimal power when no communication is present.
• When data is sent or received, the transceiver is activated and power is consumed for communication.
• The device monitors the bus and reduces power consumption by entering sleep mode, again, when communication stops.

For added protection, the ISL4270EIR-T features ESD protection on inputs, outputs, and power pins. The device also features built-in thermal protection and current limit protection.

In summary, the ISL4270EIR-T is a pre-driver/receiver device designed for use in automotive and industrial CAN communication applications. Its low power, small size, cost, and wide temperature range make it a great solution for these applications.
