描述

The SN65HVDA540/SN65HVDA541 meets or exceeds the specifications of the ISO 11898 standard for use in applications employing a Controller Area Network (CAN). The device is qualified for use in automotive applications.

As a CAN transceiver, this device provides differential transmit capability to the bus and differential receive capability to a CAN controller at signaling rates up to 1 megabit per second (Mbps)(1).

Designed for operation in especially harsh environments, the SN65HVDA540/SN65HVDA541 features cross-wire, bus over voltage, loss of ground protection, over temperature thermal shut down protection, and a wide common-mode range.

The SN65HVDA540/SN65HVDA541 has an I/O supply voltage input pin (VIO , pin 5) to ratiometrically level shift the digital logic input and output levels with repsect to VIO for compatibility with protocol controllers having I/O supply voltages between 3 V and 5.25 V. The VIO supply also powers the low-power bus monitor and wake-up receiver of the SN65HVDA541 allowing the 5 V (VCC) supply to be switched off for additional power savings at the system level during standby mode for either the SN65HVDA540 or SN65HVDA541. The 5 V (VCC) supply needs to be reactivated by the local protocol controller at any time to resume high speed operation if it has been turned off for low-power standby operation. Both of the supply pins have undervoltage detection which place the device in standby mode to protect the bus during an undervoltage event on either the VCC or VIO supply pins. If VIO is undervoltage the RXD pin is 3-statedn and the device does not pass any wake-up signals from the bus to the RXD pin.

STB (pin 8) provides for two different modes of operation: normal mode or low-power standby mode. The normal mode of operation is selected by applying a low logic level to STB. If a high logic level is applied to STB, the device enters standby mode (see Figure 1 and Figure 2). In standby mode, the SN65HVDA541 provides a wake-up receiver and monitor that remains active supplied via the VIO pin so that VCC may be removed allowing a system level reduction in standby current. A dominant signal on the bus longer than the wake-up signal time (tBUS) is passed to the receiver output (RXD, pin 4) by the wake-up bus monitor circuit. The local protocol controller may then return the device to normal mode when the system needs to transmit or fully monitor the messages on the bus. If the bus has a fault condition where it is stuck dominant while the SN65HVDA541 is placed into standby mode, the device locks out the wake-up receiver output to RXD until the fault has been removed to prevent false wake-up signals in the system. Because the SN65HVDA540 does not have a low-power bus monitor and wake-up receiver, it provides a logic high output (recessive) on RXD while in standby mode.

A dominant time-out circuit prevents the driver from blocking network communication in event of a hardware or software failure. The dominant time out circuit is triggered by a falling edge on TXD (pin 1). If no rising edge is seen before the time-out constant of the circuit expires, the driver is disabled. The circuit is reset by the next rising edge on TXD.
