CAN Transceiver


The WT1040/WT1050 is the interface between the Controller Area Network (CAN) protocol controller and the physical bus, and can be applied to the fields of trucks, buses, cars, industrial control etc. It is primarily intended for high speed applications, up to 1 MBaud, in passenger cars. The device provides differential transmit capability to the bus and differential receive capability to the CAN controller, and fully compatible with the ISO 11898 standard.

* Fully compatible with the ISO 11898 standard
* Thermally protected;
* Input levels compatible with 3.3 V and 5 V devices;
* Transmit Data (TXD) dominant time-out function;
* Very low-current standby mode with remote wake-up capability via the bus(TYP. 5uA)(WT1040);
* Silent mode in which the transmitter is disabled(WT1050);
* Transceiver in unpowered state disengages from the bus (zero load);
* At least 110 nodes can be connected;
* High speed (up to 1 MBaud);
* Very low Electro Magnetic Emission (EME);
