Chipanalog CA-IF1145FNF-Q1 Interface IC

Chipanalog CA-IF1145FNF-Q1

The CA-IF1145 devices are robust high-speed, low-power control area network (CAN) transceivers with integrated protection for automotive applications. These devices meet the requirements ISO1189-2:2016 and SAE J2284-1 to SAE J2284-5 physical layer standards. All devices feature up to ±42V extended fault protection on the data transmission lines in all operation modes. The CA-IF1145 devices can operate in different modes: normal operation, overtemperature protection mode, and standby, sleep, off modes for low current consumption, as well as wake-up capability over CAN bus or via the local WAKE pin. A selective wake-up (FD-passive) is able to ignore CAN FD(flexible data rate) frames while waiting for a valid wake-up frame in sleep or standby modes to support ISO 11898-2:2016 compliant CAN partial networking and enables reliable communication in the CAN FD networks up to 5 Mbit/s data rates. Inhibit output (INH) can be used to control one or more external voltage regulators presented on a node to reduce the battery power consumption at system level. The CA-IF1145 features ideal passive behavior when unpowered, all bus terminals are high impedance during power-off. These make the CA-IF1145 ideal in the applications that all nodes are always connected to the power supply line, because the transceivers can be active only as required to minimize system current consumption. The CA-IF1145 series devices include a dominant timeout detection to prevent bus lockup caused by controller error or by a fault on the TXD input. Also, the CA-IF1145 devices feature individual logic supply input (VIO) and provide low level translation to simplify the interface with low voltage CAN controllers. SPI-compatible interface is available for transceiver operation control and status information reading.
