TJA1050
FEATURES
Fully compatible with the “ISO 11898” standard
High speed (up to 1 Mbaud)
Very low ElectroMagnetic Emission (EME)
Differential receiver with wide common-mode range for
high ElectroMagnetic Immunity (EMI)
An unpowered node does not disturb the bus lines
Transmit Data (TXD) dominant time-out function
Silent mode in which the transmitter is disabled
Bus pins protected against transients in an automotive
environment
Input levels compatible with 3.3 V and 5 V devices
Thermally protected
Short-circuit proof to battery and to ground
At least 110 nodes can be connected.
GENERAL DESCRIPTION
The TJA1050 is the interface between the Controller Area
Network (CAN) protocol controller and the physical bus.
The device provides differential transmit capability to the
bus and differential receive capability to the CAN
controller.
The TJA1050 is the third Philips high-speed CAN
transceiver after the PCA82C250 and the PCA82C251.
The most important differences are:
Much lower electromagnetic emission due to optimal
matching of the output signals CANH and CANL
Improved behaviour in case of an unpowered node
No standby mode.
This makes the TJA1050 eminently suitable for use in
nodes that are in a power-down situation in partially
powered networks.
