ON announces NCV7341 CAN transceiver

ON Semiconductor has announced a high-speed controller area network (CAN) transceiver IC for automotive in-vehicle networking (IVN) applications.

The IC further expands the company's range of IVN parts that are certified in accordance with CAN and LIN interoperability standards.

The NCV7341 CAN transceiver, which offers low power consumption, is certified to the requirements of the Generalised Interoperable Fault Tolerant (GIFT) CAN transceiver specification and is pin compatible with devices from third parties.

As a result, designers can use the device in new IVN applications and as a 'drop-in' replacement in existing applications securing second sourcing towards end customers.

ON Semiconductor's application-specific standard product (ASSP) provides the interface between a CAN protocol controller and the physical bus and is fully compliant with the ISO 11898-5 standard for CAN physical layer transmission in automotive IVNs at rates up to 1Mbit/s.

A sleep mode and a low current standby mode (20uA) with remote wake-up via the bus provide engineers with flexibility in reducing power consumption.

In addition, an integrated inhibit switch can be used to further reduce overall power consumption by disabling external voltage regulators.

The NCV7341 offers exceptional electromagnetic capability (EMC) performance.

Careful matching of output signals and a voltage source for stabilising the recessive bus level if a split termination is used minimise electromagnetic emissions (EME) and eliminate the need for additional filtering components.

A differential receiver with a high common-mode input range helps minimise electromagnetic interface (EMI).

The NCV7341 features a number of built-in safety features including thermal protection.

Bus pins are also protected against voltage transients that are common in the noisy automotive environment.

Suitable for connecting up to 110 nodes, the IC offers microcontroller-compatible input levels for ease of design.

The device is supplied in a 14-pin SOIC package and has an operating temperature range of -40C to 125C.

The device is the latest in a series of IVN transceivers that are certified to relevant interoperability standards.

As well as GIFT-compliant CAN transceivers, ON Semiconductor also offers products such as the NCV7420 series of LIN transceivers, which are certified in accordance with the requirements of the SAE J2602-1 standard for LIN 2.0-based vehicle networks.

These devices bring together LIN transceiver and voltage regulator functionality in a single, low-power, mixed-signal chip.
