The MCP2561/2 is Microchip Technology Inc. second generation high-speed CAN transceiver. It serves as an interface between a CAN protocol controller and the physical two-wire CAN bus. The device family members are: • MCP2561 with SPLIT pin • MCP2562 with VIO pin

Supports 1 Mb/s operation
Implements ISO-11898-5 standard physical layer requirements
Very low standby current (Typ: 5μA)
VIO supply pin (MCP2562) to interface directly to CAN controllers and microcontrollers with 1.8V to 5V I/O
SPLIT output pin (MCP2561) 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
Detection of ground fault, Permanent dominant detection on TXD, Permanent dominant detection on bus
Power-on Reset and voltage brown-out protectionon VDD and VIO pin
