- Survives Shorts and Transients on Automotive Bus
- Wide Power Supply Voltage Range
- Fault Detection
- IS09141 patible
Description
The Si9243 is a monolithic bus driver designed to provide bidirectional serial munication in automotive diagnostic applications.
The device incorporates protection against overvoltages and short circuits to GND or VBA'P The transceiver pin is protected and can be driven beyond the VBATvoltage.
The temperature and short circuit fault detection feature is still active as in the Si9242, but the FAULT signal is not brought out. 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 Si9243 will tum off the K output in the event of over temperature or short circuit to protect the IC. The fault will be reset when TX toggles "high".
TX is set "high"...
