LIN and CAN transceivers

8 February 2012 Telecoms, Datacoms, Wireless, IoT

ON Semiconductor 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.

The NCV7425 features an 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 Kbps. Available in 3,3 V and 5 V output options, it supports loads up to 150 mA and is compliant with the latest automotive standards. An integrated slope control function ensures enhanced electromagnetic interference (EMI) compatibility.

The chip supports a bus voltage of ±45 V and offers onboard functions that include thermal shutdown, indefinite short circuit protection, load dump protection to 45 V, and ESD protection up to ±10 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. The device offers high-speed communication at up to 1 Mbps, while 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.

The NCV7425 and NCV7441 are AEC-Q100 qualified, and have rated operating junction temperature ranges of -40°C to +150°C and -40°C to +125°C respectively.
