CAN transceiver supports partial networking

The TJA1145 CAN transceiver supports partial networking, which can save energy and raise fuel economy in cars. Partial networking allows automotive control unit nodes to go into a low-power mode, without bus traffic, when not in use. Many accessories such as seat positioning and sun-roof operation are used infrequently.

Some automobiles have as may as 100 CAN nodes, so use of the ISO 11898-6 compliant transceiver can save considerable power. The IC supports operation with and without selective wake-up function and also delivers high EMI robustness and low EME. (Price not determined — samples available now.)
