Si9200
Vishay Siliconix
CAN Bus Driver and Receiver
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 V
DD
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 °C to 125 °C). The
Si9200EY is available in lead free.
FEATURES
• Survives Ground Shorts and Transients on
Multiplexed Bus in Automotive and Industrial Applications
• Single Power Supply
• Compatible with Intel 82526 CAN Controller
• Direct Interface - No External Components Required
• Automotive Temperature Range (- 40 °C to 125 °C)
