MAX13052：Industry-Standard High-Speed CAN Transceivers with ±80V Fault Protection

The 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 common-mode 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.
