MCP2561-E/P

The MCP2561-E/P is a high-speed CAN Transceiver serves as the interface between a CAN protocol controller and the physical bus. The MCP2561 provides differential transmit and receive capability for the CAN protocol controller and is fully compatible with the ISO-11898-5 standard. It will operate at speeds of up to 1Mb/s. Typically, each node in a CAN system must have a device to convert the digital signals generated by a CAN controller to signals suitable for transmission over the bus cabling (differential output). It also provides a buffer between the CAN controller and the high-voltage spikes that can be generated on the CAN bus by outside sources. It has under-voltage detection on both supply pins: VDD and VIO. Typical under-voltage thresholds are 1.2V for VIO and 4V for VDD. When the device is powered on, CANH and CANL remain in a high-impedance state until both VDD and VIO exceed their under-voltage levels.

• Supports 1Mb/s Operation
• Implements ISO-11898-5 standard physical layer requirements
• SPLIT Output pin to stabilize common mode in biased split termination schemes
• CAN bus pins are disconnected when device is unpowered
• An unpowered node or brown-out event will not load the CAN bus
• Permanent dominant detection on TXD
• Permanent dominant detection on bus
• Protection against damage due to short-circuit conditions
• Protection against high-voltage transients in automotive environments
• Automatic thermal shutdown protection
