Description
The Si9241 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 VB. The transceiver pin is protected and can be driven beyond the VB voltage.
A fault detector provides an active low in case of short circuit to VB or an open load prevent proper data transmission. The open drain Fault output can be wire or-ed. The CS input can be tied high for receive only interfaces.
In the event of an over temperature condition, the output is immediately switched off and a fault indicated.
This condition can...
