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.

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.
