Microchip CAN Transceivers Family (11 parts in our catalog)

Microchip CAN transceivers provide the physical layer interface between a Controller Area Network (CAN) protocol controller and the physical copper bus. Designed to meet ISO-11898-2 and ISO-11898-5 standards, these components facilitate high-speed communication up to 1 Mbps, while newer variants support CAN Flexible Data-rate (CAN FD) up to 8 Mbps. These devices are engineered for robust performance in harsh environments, featuring high ESD protection and low electromagnetic emissions to ensure signal integrity in industrial and automotive systems.

Key Features

• High-speed CAN FD support up to 8 Mbps for modern data requirements
• Low quiescent current and standby modes for power-sensitive designs
• Integrated ESD and transient protection exceeding automotive standards
• Vio pin options for direct interfacing with 1.8V to 5V microcontrollers
• Thermal shutdown and short-circuit protection for bus fault tolerance

Typical Use Cases

Microchip CAN transceivers are primarily deployed in automotive and industrial embedded systems where reliable differential signaling is critical. In automotive applications, they serve as the communication backbone for Engine Control Units (ECUs), body electronics, and advanced driver-assistance systems (ADAS), often requiring the split termination or low-power standby modes found in the MCP2561/2 series. In industrial automation, these transceivers are integrated into programmable logic controllers (PLCs), motor drives, and sensor networks operating under the CANopen or DeviceNet protocols. The family is particularly favored in designs where space is constrained and electromagnetic compatibility (EMC) is a priority, as these devices minimize radiated emissions without external filtering. They are also common in medical instrumentation and marine electronics where robust fault protection and wide operating temperature ranges are mandatory for maintaining system uptime during bus contention or ground loop issues.
