ON Semiconductor has introduced a high-speed Controller Area Network (CAN) transceiver IC, NCV7341, certified to the requirements of the Generalized Interoperable Fault Tolerant (GIFT) CAN transceiver specification.
The 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 networks at rates up to 1 megabit per second. A sleep mode and a low current (20 microamp) stand-by mode with remote wake-up via the bus help to reduce power consumption. An integrated inhibit switch can be used to further reduce overall power consumption by disabling external voltage regulators.
Careful matching of output signals, and a voltage source for stabilizing the recessive bus level if a split termination is used, minimize electromagnetic emissions and eliminate the need for additional filtering components, according to the company. A differential receiver with a high common-mode input range helps minimize electromagnetic interference (EMI).
The NCV7341 features thermal protection among other built-in safety features. Bus pins are protected against voltage transients, which are common in the noisy automotive environment.
Suitable for connecting up to 110 nodes, the new 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 -40º C to 125 ºC.
The new NCV7341 CAN transceiver is priced at $1.53 per unit in quantities of 1,000 or more.
