Texas Instruments SN65HVD233MDREP

The SN65HVD233 is used in applications employing the controller area network (CAN) serial communication physical layer in accordance with the ISO 11898 standard. As a CAN transceiver, it provides transmit and receive capability between the differential CAN bus and a CAN controller, with signaling rates up to 1 Mbps.

Designed for operation in especially harsh environments, the device features cross-wire, overvoltage and loss of ground protection to ±36 V, with overtemperature protection and common-mode transient protection of ±100 V. This device operates over a –7-V to 12-V common-mode range with a maximum of 60 nodes on a bus.

If the common-mode range is restricted to the ISO-11898 Standard range of –2 V to 7 V, up to 120 nodes may be connected on a bus. This transceiver interfaces the single-ended CAN controller with the differential CAN bus found in industrial, building automation, and automotive applications.

The RS (pin 8) of the SN65HVD233 provides for three modes of operation: high-speed, slope control, or low-power standby mode. The high-speed mode of operation is selected by connecting RS directly to ground, allowing the driver output transistors to switch on and off as fast as possible with no limitation on the rise and fall slope. The rise and fall slope can be adjusted by connecting a resistor to ground at RS, since the slope is proportional to the pin's output current. Slope control is implemented with a resistor value of 10 k to achieve a slew rate of 15 V/µs and a value of 100 k to achieve 2.0 V/µs slew rate. For more information about slope control, refer to the application information section.

The SN65HVD233 enters a low-current standby mode during which the driver is switched off and the receiver remains active if a high logic level is applied to RS. The local protocol controller reverses this low-current standby mode when it needs to transmit to the bus.

A logic high on the loopback LBK (pin 5) of the SN65HVD233 places the bus output and bus input in a high-impedance state. The remaining circuit remains active and available for driver to receiver loopback, self-diagnostic node functions without disturbing the bus.
