CAN Transceiver
Description The device B10011S is a transceiver for CAN bus systems This device contains a fault recognition circuit for faults with high transmission levels according to on one of the two wires which are normally used for trans- ISO WD 11992-1 (point-to-point interface between mission. If a fault occurs on one of the wires, the operation trucks and trailers). The special features of a circuit can be switched from double-wire to single-wire mode, containing this device allow transmission which is thus allowing proper operation even if one wire is broken, insensitive to electromagnetic interference that can has a short-cut or a high series resistance. appear particularly in truck applications, where, due to the length of the wires, high common-mode voltages (e.g., 50 V) can be coupled into the lines.
Features Benefits
The CAN driver B10011S is a low-speed, high-level Systems which employ this device have the following interface for 24-V (27-V) operation. It is developed for benefits in comparison with solutions using discrete signal levels of 8/16 V and a speed of up to 250 kbits/s. components:
Special features are:
Capability of single-wire operation
Especially suited for truck and van applications Hardware fault recognition
Interface between truck and trailer Inputs with high common-mode and differential- mode interference rejection above 100 VPP due to
Interface between dashboard and engine
external filters at the receiver input
High reliability Immunity against electromagnetic interference
