Texas Instruments SN65HVD230DR

The SN65HVD230, SN65HVD231, and SN65HVD232 controller area network (CAN) transceivers are compatible to the specifications of the ISO 11898-2 High Speed CAN Physical Layer standard (transceiver). These devices are designed for data rates up to 1 megabit per second (Mbps), and include many protection features providing device and CAN network robustness. The SN65HVD23x transceivers are designed for use with the Texas Instruments 3.3 V µPs, MCUs and DSPs with CAN controllers, or with equivalent protocol controller devices. The devices are intended for use in applications employing the CAN serial communication physical layer in accordance with the ISO 11898 standard.

Designed for operation in especially harsh environments, these devices feature cross wire protection, loss of ground and overvoltage protection, overtemperature protection, as well as wide common mode range of operation.

The CAN transceiver is the CAN physical layer and interfaces the single ended host CAN protocol controller with the differential CAN bus found in industrial, building automation, and automotive applications. These devices operate over a -2 V to 7 V common mode range on the bus, and can withstand common mode transients of ±25 V.

The RS pin (pin 8) on the SN65HVD230 and SN65HVD231 provides three different modes of operation: high speed mode, slope control mode, and low-power mode. The high speed mode of operation is selected by connecting the RS pin to ground, allowing the transmitter output transistors to switch on and off as fast as possible with no limitation on the rise and fall slopes. The rise and fall slopes can also be adjusted by connecting a resistor in series between the RS pin and ground. The slope will be proportional to the pin’s output current. With a resistor value of 10 k? the device will have a slew rate of ~15 V/µs, and with a resistor value of 100 k? the device will have a slew rate of ~2 V/µs. See Application Information for more information.

The SN65HVD230 enters a low current standby mode (listen only) during which the driver is switched off and the receiver remains active if a high logic level is applied to the RS pin. This mode provides a lower power consumption mode than normal mode while still allowing the CAN controller to monitor the bus for activity indicating it should return the transceiver to normal mode or slope control mode. The host controller (MCU, DSP) returns the device to a transmitting mode (high speed or slope control) when it wants to transmit a message to the bus or if during standby mode it received bus traffic indicating the need to once again be ready to transmit.

The difference between the SN65HVD230 and the SN65HVD231 is that both the driver and the receiver are switched off in the SN65HVD231 when a high logic level is applied to the RS pin. In this sleep mode the device will not be able to transmit messages to the bus or receive messages from the bus. The device will remain in sleep mode until it is reactivated by applying a low logic level on the RS pin.

德克萨斯仪器SN65 HVD230DR
SN65 HVD230、SN65 HVD23 1和SN65 HVD22控制器局域网(CAN)收发器兼容ISO11898-2高速CAN物理层标准(收发器)。这些设备被设计用于高达1兆比特每秒(Mbps)的数据速率,并且包括提供设备和CAN网络稳健性的许多保护特性。SN65 HVD23 X收发器被设计用于与德克萨斯仪器3.3 VPS PS、MCU和DSPs一起使用CAN控制器,或与等效协议控制器设备一起使用。该设备用于根据ISO 11898标准使用CAN串行通信物理层的应用。
设计用于恶劣环境下的操作,这些设备具有十字线保护、接地和过电压保护、超温保护以及宽共模范围的操作。
CAN收发器是CAN物理层,并与工业、楼宇自动化和汽车应用中的差分CAN总线接口的单端主机CAN协议控制器。这些器件在总线上运行在-V至2 V共模范围,并能承受±25 V的共模瞬态。
在SN65 HVD230和SN65 HVD221上的RS引脚(引脚8)提供三种不同的操作模式:高速模式、斜率控制模式和低功耗模式。高速操作模式是通过将RS引脚连接到接地而选择的,允许发射器输出晶体管尽可能快地接通和断开,而不限制上升和下降斜率。上升和下降斜率也可以通过在RS引脚和接地之间串联电阻来调节。斜率将与管脚的输出电流成比例。当电阻值为10 K时,器件的转换速率将达到15伏/秒,电阻值为100 K时,器件的转换速率将达到2伏/秒。
SN65 HVD230进入低电流待机模式(只读),在此期间,如果将高逻辑电平应用到RS引脚,则驱动器断开,并且接收器保持活跃。这种模式提供了比正常模式更低的功耗模式,同时仍然允许CAN控制器监视总线的活动,指示它应该将收发器返回到正常模式或斜率控制模式。主机控制器(MCU,DSP)在想要向总线发送消息时,将设备返回到传输模式(高速或斜率控制),或者如果在待机模式下,它接收到表明需要再次发送的总线流量。
SN65 HVD230与SN65 HVD23 1之间的区别在于,当在RS-引脚上应用高逻辑电平时,驱动器和接收器都在SN65 HVD23中被关断。在这种睡眠模式中,设备将无法向总线发送消息或从总线接收消息。该装置将保持在睡眠模式,直到它被重新激活,通过在RS引脚上应用低逻辑电平。
