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 giving the following advantages:
An unpowered node does not disturb the bus lines.
Low current sleep/standby mode with wake-up via the
bus lines
Power-on reset flag on the output.
Better equipped for networks with more than 15 nodes
Integrated timer at the TXD input prevents a permanent
dominant state
Reduced supply current in V
CANH output driver is disabled in the event of a ‘CANH
short-circuited to battery’ failure mode.
