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 meets the automotive requirements for high-speed (1 Mb/s), low quiescent current, electromagnetic compatibility (EMC) and electrostatic discharge (ESD). The device family members are: • MCP2561 with SPLIT pin • MCP2562 with VIO pin

• Supports 1 Mb/s operation
• Implements ISO-11898-5 standard physical layerrequirements
• AEC-Q100 Grade 0
• 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
• Protection against damage due to short-circuitconditions (positive or negative battery voltage)
• Protection against high-voltage transients in automotive environments
• Automatic Thermal Shutdown protection
• Suitable for 12V and 24V systems
• Up to 112 nodes can be connected
• High-noise immunity due to differential bus implementation
• High ESD protection on CANH and CANL, IEC61000-4-2 > 8kV
• Available in PDIP-8L, SOIC-8L and 3x3 DFN-8L.
• Temperature ranges; Extended (E): -40°C to +125°C, High (H): -40°C to +150°C
