MCP2551
High-Speed CAN Transceiver
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
