B10011S
Description
The CAN driver IC B10011S is a low-speed, high-level interface for 24 V (27 V) opera-
tion with transmission levels according to ISO WD 11992-1 (point-to-point interface
between trucks and trailers). It is developed for signal levels of 8/16 V and a speed of
up to 250 kbits/s.

This device allows transmission, that is insensitive to electromagnetic interference.
Such interferences may especially occur in truck applications where (due to the length
of the wires) high common-mode voltages (e.g., 50 ) can be coupled into the lines.
This device contains a fault recognition circuit that detects faults on one of the two
wires, which are normally used for transmission. If a fault occurs the operation can be
switched from double-wire to single-wire mode thus, allowing proper operation even if
one wire is broken, has a short-cut or a high series resistance.

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Two-wire operation, normal mode
ER (error signal) is low when normal operation is disturbed by line faults (interruption,
short to ground or to VCC, H to L short disturbance by high voltage transients). After a
waiting period due to transient delays, the controller is asked to test if single-wire opera-
tion is possible by changing the Asel and Bsel state.
Asel and Bsel have an internal pull-up resistor. Therefore, the no-connect state is 1, but
connection to VDD is recommended when not in use.
