GENERAL DESCRIPTION

The ADM3051 is a controller area network (CAN) physical layer transceiver allowing a protocol layer CAN controller to access the physical layer bus. The ADM3051 complies with the ISO 11898 standard. It is capable of running at data rates up to 1 Mbps.

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 24 V bus power systems. The part is fully specified over the industrial temperature range of −40°C to +125°C and is available in an 8-lead SOIC package.

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.

CIRCUIT DESCRIPTION

CAN TRANSCEIVER OPERATION

A CAN bus has two states: dominant and recessive. A dominant state is present on the bus when the differential voltage between CANH and CANL is greater than 0.9 V. A recessive state is present on the bus when the differential voltage between CANH and CANL is less than 0.5 V. During a dominant bus state, the CANH pin is high and the CANL pin is low. During a recessive bus state, both the CANH and CANL pins are in the high impedance state.

The driver drives CANH high and CANL low (dominant state) if a logic low is present on TxD. If a logic high is present on TxD, the driver output is placed in a high impedance state (recessive state). The driver output states are shown in Tabl e 7 .

The receiver output is low if the bus is in the dominant state and high if the bus is in the recessive state. If the differential voltage between CANH and CANL is between 0.5 V and 0.9 V, the bus state is indeterminate and the receiver output may be high or low. The receiver output states for given inputs are listed in Tabl e 8.

OPERATIONAL MODES

Three modes of operation are available: high speed, slope control, and standby. RS (Pin 8) allows modification of the operational mode by connecting the RS input through a resistor to ground, or directly to ground, or to a CAN controller, as shown in Figure 30.

With RS connected to ground, the output transistors switch on and off at the maximum rate possible in high speed mode, with no modification to the rise and fall slopes. EMI in this mode can be alleviated using shielded cables.

Alternatively, connecting RS to a resistor, R slope control mode, with the value of the resistor modifying the rise and fall slopes. The reduced EMI allows the use of unshielded cables.

Applying a logic high to RS initiates a low current standby mode. The transmitter is disabled, and the receiver is connected to a low current. RxD goes low upon receiving dominant bits, allowing an attached microcontroller that detects this to wake the transceiver via Pin 8, which returns it to standard operation. The receiver is slower in standby mode and loses the first message at higher bit rates.

THERMAL SHUTDOWN

The ADM3051 contains thermal shutdown circuitry that protects the part from excessive power dissipation during fault conditions. Shorting the driver outputs to a low impedance source can result in high driver currents. The thermal sensing circuitry detects the increase in die temperature under this condition and disables the driver outputs. The design of this circuitry ensures the disabling of driver outputs upon reaching a die temperature of 150°C. As the device cools, reenabling of the drivers occurs at a temperature of 140°C.
