概述
Description
The SN65HVD485EDGKR is a 3.3V CAN transceiver from Texas Instruments, designed for Controller Area Network (CAN) applications. It supports CAN FD (Flexible Data Rate) for high-speed communication up to 5 Mbps, making it suitable for automotive, industrial, and embedded systems.
Key features:
- ISO 11898-2 compliant
- Low-power standby mode (10 µA typical)
- ±30V fault protection on bus pins
- Wide common-mode range (±12V) for noise immunity
- 8-pin VSSOP (DGK) package
It integrates driver, receiver, and protection circuits, ensuring robust communication in harsh environments. The device operates from 3.3V supply, making it ideal for low-power applications.
Typical uses include automotive ECUs, industrial automation, and CAN bus networks. Its small form factor and high reliability make it a popular choice for space-constrained designs.
For detailed specs, refer to the TI datasheet (SN65HVD485E).
