MCP2551ESLASHP中文资料微芯科技数据手册PDF规格书

DEVICE OVERVIEW

The MCP2551 is a high-speed CAN, fault-tolerant device that serves as the interface between a CAN protocol controller and the physical bus. The MCP2551 device provides differential transmit and receive capability for the CAN protocol controller, and is fully compatible with the ISO-11898 standard, including 24V requirements. It will operate at speeds of up to 1 Mb/s.

特性 Features

• Supports 1 Mb/s operation

• Implements ISO-11898 standard physical layer

requirements

• Suitable for 12V and 24V systems

• Externally-controlled slope for reduced RFI

emissions

• Detection of ground fault (permanent Dominant)

on TXD input

• Power-on Reset and voltage brown-out protection

• An unpowered node or brown-out event will not

disturb the CAN bus

• Low current standby operation

• Protection against damage due to short-circuit

conditions (positive or negative battery voltage)

• Protection against high-voltage transients

• Automatic thermal shutdown protection

• Up to 112 nodes can be connected

• High-noise immunity due to differential bus

implementation

• Temperature ranges:

- Industrial (I): -40°C to +85°C

- Extended (E): -40°C to +125°C
