Philips Semiconductors
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.
