MCP2557FD/8FD
CAN FD Transceiver with Silent Mode
Features
Description
•
Silent Mode is Useful in the Following
Applications:
The MCP2557FD/8FD CAN transceiver family is
designed for high-speed CAN FD applications with up
to 8 Mbps communication speed. The maximum prop-
agation delay was improved to support longer bus
length.
- Disables transmitter in redundant systems
- Implements babbling idiot protection
- Tests connection of bus medium
The device meets automotive requirements for CAN
FD bit rates exceeding 2 Mbps, low quiescent current,
electromagnetic compatibility (EMC) and electrostatic
discharge (ESD).
- Prevents
disrupting all network communications
a faulty CAN controller from
• Optimized for CAN FD at 2, 5 and 8 Mbps
Operation:
- Maximum propagation delay: 120 ns
- Loop delay symmetry: ±10%(2 Mbps)
