MAX3055

±80V Fault-Protected/Tolerant CAN Transceivers for In-Car Applications

Industry's First ±80V Fault Protected and Fault Tolerant CAN Transceiver Is ideal for 42V Battery Systems


Please check latest availability status for a specific part variant.

Description

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-wire mode if certain fault conditions occur. The MAX3054/MAX3055/MAX3056 guarantee full wake-up capability during failure modes.

The extended fault-protected voltage range of CANH and CANL bus lines of ±80V allows for use in 42V high-voltage applications. Current-limiting and thermal-protection 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 an rugged environment.

The transceiver provides three low-power modes that can be entered and exited through pins STB-bar and EN. An output INH pin can be used for deactivation of an external voltage regulator.

The MAX3054/MAX3055/MAX3056 are designed to provide optimal operation for a specified data rate. The MAX3054 is ideal for high data rates of 250kbps. The MAX3055 is used for data rates of 125kbps and the MAX3056 is designed for 40kbps applications. For the 40kbps and 125kbps versions, a built-in slope-control feature allows the use of unshielded cables, and receiver input filters guarantee high noise immunity.
