Microchip High Speed CAN Transceiver 1Mbps SOIC-8

The Microchip High Speed CAN Transceiver serves as a reliable interface between a CAN protocol controller and the physical bus. Providing differential transmit and receive capability, this device is fully compatible with the ISO-11898 standard, including 24V requirements, and operates at speeds of up to 1Mb/s.

Each node in a CAN system requires a device to convert digital signals from the controller into signals suitable for transmission over the bus cabling. This transceiver also acts as a buffer, protecting the CAN controller from high voltage spikes generated on the bus by external sources such as EMI, ESD, and electrical transients.

Key Features and Protection

• Supports 1Mb/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

Please note: This device is not recommended for new designs.

With robust protective features and high noise immunity, this transceiver ensures stable communication in demanding environments.
