Description
The SN65HVD231D is a high-speed, low-power transceiver designed for Controller Area Network (CAN) applications. Developed by Texas Instruments, it is part of the SN65HVD23x family and is used for automotive and industrial communications. The device supports a data rate of up to 1 Mbps, making it suitable for high-speed CAN networks.
The transceiver is designed to interface between the CAN protocol controller and the physical bus. It features three operating modes: high-speed, slope control, and low-power standby, providing flexibility and efficient power management. The slope control mode helps minimize electromagnetic interference (EMI) by controlling the signal rise and fall times, while the low-power standby mode reduces power consumption when the device is not in use.
The SN65HVD231D offers several protection features, including thermal shutdown, overvoltage protection, and a dominant-time-out function, which prevents bus lock-up. It operates over a wide voltage range (3.0V to 3.6V) and can withstand common automotive conditions, making it robust for various environments. Its compact SOIC-8 package ensures easy integration into circuit designs.
