2 Applications • CAN Data Buses • Industrial Automation • SAE J1939 Standard Data Bus Interface • NMEA 2000 Standard Data Bus Interface D1 GND 2 Block Diagram Overtemperature Sensor Vcc (3) VCC (3) SLOPE CONTROL and MODE LOGIC VCC (3) VCC/2 VREF (5) 8 RS Driver 7 CANH VCC 3 6 CANL R4 5 VREF 3 Description The HVD251 is intended for use in applications employing the Controller Area Network (CAN) serial communication physical layer in accordance with the ISO 11898 Standard.
The HVD251 provides differential transmit capability to the bus and differential receive capability to a CAN controller at speeds up to 1 megabits per second (Mbps).
Designed for operation in harsh environments, the device features cross-wire, overvoltage and loss of ground protection to ±36 V.
Also featured are overtemperature protection as well as –7-V to 12-V common-mode range, and tolerance to transients of ±200 V.
The transceiver interfaces the single-ended CAN controller with the differential CAN bus found in industrial, building automation, and automotive applications.
Rs, pin 8, selects one of three different modes of operation: high-speed, slope control, or low-power mode...
