B10011S Datasheet | Atmel

Features - Capability of Single-wire Operation - Hardware Fault Recognition - Inputs with High mon-mode and Differential-mode Interference Rejection Above 100 VPP due to External Filters at the Receiver Input - Immunity Against Electromagnetic Interference - Immunity Against Ground-voltage Offsets < 6 V - Ruggedized Against ESD by MIL-STD-883C, Method 3015 Benefits Systems which employ this device have the following benefits pared to solutions using discrete ponents: - High Reliability CAN Transceiver IC B10011S Applications - Especially Suited for Truck and Van Applications - Interface Between Truck and Trailer - Interface Between Dashboard and Engine Description The CAN driver IC B10011S is a low-speed, high-level interface for 24 V (27 V) operation 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 mon-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. Figure 1.
