ADM3051CRZ Datasheet PDF - ADI

●The ADM3051 series controller area network (CAN) Physical Layer Transceiver allowing a protocol layer CAN controller to access the physical layer bus. It is capable of running at data rates up to 1Mbps. The device has current-limiting and thermal shutdown features to protect against output short circuits and situations where the bus may be shorted to ground or power terminals in 24V bus power systems. Three operating modes are available: high speed, slope control and standby. Pin 8 (RS) is used to select the operating mode. The low current standby mode can be selected by applying a logic high to RS. The device can be set to operate with slope control to limit EMI by connecting RS with a resistor to ground to modify the rise and fall of slopes. This mode facilitates the use of unshielded cables. Alternatively, disabling slope control by connecting RS to ground allows high speed operation. Shielded cables or other measures to control EMI are necessary in this mode.

● High speed data rates up to 1Mbps

● Short-circuit protection on CANH and CANL against shorts to power/ground in 24 V systems

● Unpowered nodes do not disturb the bus

● Connect 110 or more nodes on the bus

● Slope control for reduced EMI

● Thermal shutdown protection

● Low current standby mode
