XL1049T/3

The XL1049 high-speed CAN transceiver provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for highspeed CAN applications in the automotive industry, supplying the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. The XL1049 belongs to the second generation of high-speed CAN transceivers, offering significant improvements over first-and second-generation devices such as the XL1040. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features: - Ideal passive behavior to the CAN bus when the supply voltage is off - A very low-current Standby mode with bus wake-up capability - XL1049T/3 can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V The XL1049 implements the CAN physical layer as defined in ISO 11898-2:2016. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s. These features make the XL1049 an excellent choice for all types of HS-CAN networks, in nodes that require a low-power mode with wake-up capability via the CAN bus. The XL1049 is a HS-CAN stand-alone transceiver with Standby mode. It combines the functionality of the XL1040 transceivers with improved EMC and ESD handling capability and quiescent current performance. Improved slope control and high DC handling capability on the bus pins provide additional application flexibility.
