1. Describe

MCP2562-E/P is Microchip Technology Inc.'s second-generation high-speed CAN transceiver. It serves as the interface between the CAN protocol controller and the physical two-wire CAN bus. This device satisfies the high speed (up to 1Mb/s), low quiescent current, electromagnetic compatibility (EMC) and electrostatic discharge (electrostatic discharge) of automobiles.

2. Device Description

MCP2561/2 is a high-speed CAN fault-tolerant device used as an interface between the CAN protocol controller and the physical bus. The MCP2561/2 device provides differential transmit and receive functions for the CAN protocol controller, and is fully compatible with ISO-11898-2 and ISO-11898-5 standards. It will run at speeds up to 1Mb/s. Generally, each node in the CAN system must have a device to convert the digital signal generated by the CAN controller into a signal suitable for transmission through the bus cable (differential output). It also provides a buffer between the CAN controller and the high voltage spikes generated on the CAN bus by an external source.

3. Feature

    1. Support 1Mb/s operation

    2. Implement ISO-11898-2 and ISO-11898-5

        - Standard physical layer requirements

    3. Very low standby current (5μA, typical value)

    4. The VIO power supply pin is directly connected to

        - CAN controller and microcontroller

        - 1.8V to 5.5V input/output

    5. Separate output pins for stabilizing common mode in a biased split termination scheme

    6. The CAN bus pins are disconnected when the device is powered off

        - Unpowered nodes or power-down events will not load the CAN bus

    7. Ground fault detection:

        - Permanent overt detection on TXD

        - Permanent overt detection on the bus

    8. Power-on reset and voltage power-down protection on VDD pin

    9. Prevent damage caused by short circuit conditions (positive or negative battery voltage)

  10. Prevent high voltage transients in the automotive environment

  11. Automatic thermal shutdown protection

  12. Suitable for 12V and 24V systems

  13. Meet or exceed stringent automotive design requirements, including "Hardware Requirements for LIN, CAN and FlexRay Interfaces in Automotive Applications", Version 1.3, May 2012

  14. High noise immunity due to differential bus implementation

  15. High Electrostatic Discharge (ESD) protection on CANH and CANL, in accordance with IEC61000-4-2 up to ±14kV

  16. Provide PDIP-8L, SOIC-8L and 3x3DFN-8L

  17. temperature range:

        - Extended (E): -40°C to +125°C

        - High (H): -40°C to +150°C
