ON Semiconductor, a premier supplier of
high performance silicon solutions for energy efficient electronics, has
launched two new integrated transceiver devices for use in local interconnect
network (LIN) and control area network (CAN) designs in automotive and
industrial applications.
Both transceivers 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 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,” said Jim Alvernez, director of the
automotive product division at ON Semiconductor.
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).
The NCV7425 is available in 3.3 volt (V)
and 5 V output options. It also supports loads up to 150 milli amperes (mA) and
is compliant with the latest automotive standards. An integrated slope control
function ensures enhanced electromagnetic interference (EMI) compatibility.
An under-voltage detection circuit provides
a reset output to a host microcontroller. The device’s INH output can be used
to manage auxiliary circuitry, including control of an external LDO.
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).
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), and 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.
