Introducing Microchip's New High-Speed CAN
Transceiver Family
MCP2561/2: Low Power and Highly Robust
Summary
The MCP2561/2 is a 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 (up to 1 Mb/s),
low-quiescent current, and high electromagnetic
compatibility (EMC).
Features
■ Supports 1 Mb/s operation
■ Implements ISO-11898-5 standard physical
layer requirements
■ Industry low standby current (<5 uA, typical)
■ Vio supply pin to interface directly to CAN controllers
and microcontrollers with 1.8V to 5.5V I/O
■ 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
■ Detection of ground fault:
• Permanent dominant detection on TXD
• Permanent dominant detection on bus
■ Power-on reset and voltage brown-out protection on
VDD and Vio pin
■ Protection against damage due to short-circuit
conditions (positive or negative battery voltage)
■ Protection against high-voltage transients in
automotive environments
■ Automatic thermal shutdown protection
■ Suitable for 12V and 24V systems
■ Meets or exceeds stringent automotive design
requirements including "Hardware Requirements
for LIN, CAN and FlexRay Interfaces in Automotive
Applications", Version 1.3, May 2012
■ High-noise immunity due to differential
bus implementation
■ Industry high ESD protection on CANH and CANL pins,
up to ±14 kV
■ Available in 8-pin PDIP, 8-pin SOIC and
3 x 3 mm 8-pin DFN
Temperature ranges:
• Industry standard pinout
• Extended (E): -40°C to +125°C
• High (H): -40°C to +150°C
High-Speed CAN Transceiver
• Approved by major automotive
and industrial OEMs
• ESD performance up to 14 kV
