Automotive-qualified integrated circuits save space and system cost in vehicle comfort and convenience, and industrial designs
PHOENIX, Ariz. - ON Semiconductor (Nasdaq: ONNN), a premier supplier of high performance silicon solutions for energy efficient electronics, has introduced two new integrated transceiver devices for use in local interconnect network (LIN) and control area network (CAN) designs in automotive and industrial applications. Both the NCV7425 LIN+LDO transceiver and NVC7441 dual CAN transceiver offer a robust, space saving and cost-effective solution for next-generation automotive 'convenience' applications as well as LIN and CAN based industrial designs.
The NCV7425 features integrated voltage regulator and reset functionality. The LIN version 2.x /SAE J2602 device interfaces between a LIN protocol controller and the physical bus, and supports transmission rates of up to 20 kilobits per second (kb/s). Available in 3.3 volt (V) and 5 V output options, the NCV7425 supports loads up to 150 milliamperes (mA) and is compliant with the latest automotive standards. An integrated slope control function ensures enhanced electromagnetic interference (EMI) compatibility.
The NCV7425 supports a bus voltage of ±45 V and offers on-board functions that include thermal shutdown, indefinite short-circuit protection, load dump protection to 45 V, and ESD protection up to ±10 kilovolts (kV). An under-voltage detection circuit provides a reset output to a host microcontroller, while the device's INH output can be used to manage auxiliary circuitry including control of an external LDO.
The NCV7441 integrates two fully independent high-speed CAN transceivers which can be individually connected to two CAN protocol controllers. The CAN channels can be separately put to normal or low current standby mode in which remote wake-up from the bus is possible. This feature reduces overall power consumption, and provides an additional benefit to the cost and space savings achieved by replacing two single CAN transceivers with a dual transceiver housed in one package.
The NCV7441 offers high-speed communication at up to 1 megabit per second (Mb/s), while excellent ESD performance in excess of ±10 kV ensures reliable communication in harsh automotive and industrial environments. Low electromagnetic emissions alleviate the need for an external choke further reducing component count, board space and cost.
The NCV7425 and NCV7441 are AEC-Q100 qualified, and have rated operating junction temperature ranges of -40 ºC to +150 ºC and -40 ºC to +125 ºC respectively.
"The use of LIN and CAN networks has allowed the cost effective implementation of a wide variety of functions in modern vehicles, such as mirror adjustment, seat adjustment, sunroof opening/closing and door lock mechanisms," says Jim Alvernez, director of the automotive product division at ON Semiconductor. "By selecting the feature rich NCV7425 and NCV7441 transceiver devices, engineers will be able to develop automotive comfort systems that require less board space, save power, and have considerably lower overall component counts."
Packaging and Pricing
The NCV7425 is offered in a Pb-free, RoHS-compliant SOIC-16 WB EP package, and is priced at $0.84 per unit in 1,500 unit quantities. The NCV7441 is offered in a Pb-free, RoHS-compliant SOIC-14 package, and is priced at $0.95 in 3,000 unit quantities.
