Product Information

Features • Capability of Single-wire Operation • Hardware Fault Recognition • Inputs with High Common-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 compared to solutions using discrete components: • 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. www.DataSheet4U.com 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. Figure 1.

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.
