The SIT3051 is the interface between the Controller Area Network (CAN) protocol controller and the physical bus. It is designed for use with the 3. 3V µPs, MCUs and DSPs with CAN controllers, or with equivalent protocol controller devices. It supports four operation modes: high-speed, slope-control, standby and low current off and common model can reach up to -7V~+12V. It is used in industrial automation, control, sensors and drive systems, motor and robotic control, building and climate control (HVAC), telecom and base station control and status.
