Philips Semiconductors
Preliminary specification
Fault-tolerant CAN transceiver
TJA1053
FEATURES
Optimized for in-car low-speed communication
Baud rate up to 125 kbaud
Up to 32 nodes can be connected
Supports unshielded bus wires
Low RFI due to built-in slope control function
Fully integrated receiver filters
Permanent dominant monitoring of TXD.
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 TJA1053 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. The TJA1053 is derived from
the PCA82C252.
1.
It is better equipped for networks with more than
15 nodes
2.
A timer has been integrated at the TXD input to
prevent a permanent dominant state
3.
Reduced supply current in V
CC
standby mode
4.
CANH output driver is disabled in the event that CANH
is short-circuited to battery failure mode.
