Fault-tolerant CAN transceiver
Product specification
PCA82C252
FEATURES
Optimized for in-car low-speed communication
• Baud rate up to 125 kBaud
• Up to 15 nodes can be connected
• Supports unshielded bus wires
• Low RFI due to built-in slope control function
• Fully integrated receiver filters.
Bus failure management
• Supports one-wire transmission modes with ground
offset voltages up to 1.5 V
• Automatic switching to single-wire mode in the event of
bus failure
• Automatic reset to differential mode if bus failure is
removed.
Protection
• Short-circuit proof to battery and ground in 12 V
powered systems
• Thermally protected
• Bus lines protected against transients in an automotive
environment
• An unpowered node does not disturb the bus lines.
Support for low-power modes
• Low current sleep/standby mode with wake-up via the
bus lines
• Power-on reset flag on the output.
GENERAL DESCRIPTION
The PCA82C252 is the interface between the CAN
protocol controller and the physical bus. It is primarily
intended for low-speed applications, up to 125 kBaud, in
passenger cars. The device provides differential transmit
capability but will switch in error conditions to a single-wire
transmitter and/or receiver.
