MAX3056 Overview
The MAX3054/MAX3055/MAX3056 are interfaces between the protocol controller and the physical wires of the bus lines in a controller area network (CAN). The devices provide differential transmit capability and switch to single-mode if certain fault conditions occur. The MAX3054/MAX3055/MAX3056 guarantee full wakeup capability during failure modes. The extended fault-protected voltage range of CANH and CANL bus lines of ±80V. Current-limiting and thermalprotection circuits protect the transmitter output stage against overcurrent faults to prevent destruction of the transmitter output stage. The CANH and CANL lines are also protected against electrical transients that may occur in rugged environments. The transceiver provides three low-power modes that can be entered and exited through pins STB and EN. An output INH pin can be used for deactivation of an external voltage regulator.
