SI9200

Si9200EY Vishay Siliconix CAN Bus Driver and Receiver FEATURES D Survives Ground Shorts and Transients on Multiplexed Bus in Automotive and Industrial Applications D Single Power Supply D Compatible with Intel 82526 CAN Controller D Direct Interface – No External Components Required D Automotive Temperature Range (–40 to 125_C) DESCRIPTION The Si9200EY is designed to interface between the Intel 82526 CAN controller and the physical bus to provide drive capability to the bus and differential receive capability to the controller. It is designed to absorb typical electrical transients on the bus which may occur in an automotive or industrial application, and protect itself against any abnormal bus conditions. The transmitter will be disabled during these conditions and will be re-enabled when the abnormal condition is cleared. The Si9200EY is built using the Siliconix BiC/DMOS process. This process supports CMOS, DMOS, and isolated bipolar transistors and uses an epitaxial layer to prevent latchup. The bus line pins are diode protected and can be driven beyond the VDD to ground range. The Si9200EY is offered in the space efficient 8-pin high-density surface-mount plastic package and is specified over the automotive temperature range (–40 to 125_C).
