Fault Detection
ISO 9141 Compatible
Description
The Si9243EY is a monolithic bus transceiver designed to
provide bidirectional serial communication in automotive
diagnostic applications.
The device incorporates protection against overvoltages
and short circuits to GND or V
B
. The transceiver pin is
protected and can be driven beyond the V
BAT
voltage.
The Si9243EY contains temperature and short circuit
fault detection circuits. In the transmit mode, load shorts
and opens are generally detected by the processor
monitoring RXK and TX. When the two mirror each other
there is no fault, but the Si9243EY will turn off the K
output in the event of over temperature or short circuit to
V
BAT
to protect the IC. The fault will be reset when TX
toggles “high.”
TX is set “high” for receive only.
The RX output is capable of driving CMOS or
1
LSTTL load.
The Si9243EY is built on the Siliconix BiC/DMOS
process. This process supports bipolar transistors,
CMOS, and DMOS. An epitaxial layer prevents latchup.
The Si9243EY is available in a 8-pin SO package and
operates over the automotive temperature range (–40 to
125 C).
