Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe MAX13050/MAX13052/MAX13053/MAX13054 are pin-for-pin compatible, industry-standard, high-speed, control area network (CAN) transceivers with extended ±80V fault protection. These products are ideal automotive and industrial network applications where overvoltage protection is required. These CAN transceivers provide a link between the CAN protocol controller and the physical wires of the bus lines in a CAN. These devices can be used for +12V/+42V battery, automotive, and DeviceNet® applications, requiring data rates up to 1Mbps.
The CAN transceivers have an input common-mode range greater than ±12V, exceeding the ISO11898 specification of -2V to +7V, and feature ±8kV ESD protection, making these devices ideal for harsh automotive and industrial environments.
The CAN transceivers provide a dominant timeout function that prevents erroneous CAN controllers from clamping the bus to a dominant level if the TXD input is held low for greater than 1ms. The MAX13050/MAX13052 provide a SPLIT pin used to stabilize the recessive commonmode voltage. The MAX13052 also has a slope-control mode that can be used to program the slew rate of the transmitter for data rates of up to 500kbps. The MAX13053 features a silent mode that disables the transmitter. The MAX13053 also has a reference output that can be used to bias the input of older CAN controllers that have a differential comparator. The MAX13054 has a separate dedicated logic input, VCC2, allowing interfacing with a +3.3V microcontroller.
The MAX13050/MAX13052/MAX13053/MAX13054 are available in an 8-pin SO package and are specified to operate in the -40°C to +85°C and the -40°C to +125°C temperature ranges.
