33790
The 33790 is a dual channel physical layer interface IC for the
Distributed System Interface (DSI) bus. It is designed to meet
automotive requirements. It can also be used in non automotive
applications. It supports bidirectional communication between slave
and master ICs. Some slave devices derive a regulated 5.0 V from
the bus, which can be used to power sensors, thereby eliminating the
need for additional circuitry and wiring. This device is powered by
SMARTMOS technology.
Features
• Two independent DSI compatible buses
• Wave-shaped bus output voltage
• Independent thermal shutdown and current limit
• Return signalling current detection
• Internal logic input pull-ups and pull-downs
• On-board charge pump
• 2.0 kV ESD capability
• Communications rate up to 150 kbps
