DESCRIPTION

The SN65HVD230Q, SN65HVD231Q, and SN65HVD232Q controller area network (CAN) transceivers are

designed for use with the Texas Instruments TMS320Lx240x 3.3-V DSPs with CAN controllers, or with

equivalent devices. They are intended for use in applications employing the CAN serial communication physical

layer in accordance with the ISO 11898 standard. Each CAN transceiver is designed to provide differential

transmit capability to the bus and differential receive capability to a CAN controller at speeds up to 1 Mbps.

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.

The transceiver interfaces the single-ended CAN controller with the differential CAN bus found in industrial,

building automation, and automotive applications. It operates over a – 2-V to 7-V common-mode range on the

bus, and it can withstand common-mode transients of

±25 V.

high-speed, slope control, and low-power modes. The high-speed mode of operation is selected by connecting

pin 8 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 be adjusted by connecting a resistor to ground

at pin 8, since the slope is proportional to the pin’s output current. This slope control is implemented with external

resistor values of 10 k

Ω, to achieve a 15-V/µs slew rate, to 100 kΩ, to achieve a 2-V/µs slew rate.

The circuit of the SN65HVD230Q enters a low-current standby mode during which the driver is switched off and

low-current standby mode when a dominant state (bus differential voltage > 900 mV typical) occurs on the bus.

The unique difference between the SN65HVD230Q and the SN65HVD231Q is that both the driver and the

The SN65HVD232Q is a basic CAN transceiver with no added options; pins 5 and 8 are NC, no connection.
