TH8056
Enhanced Single Wire CAN Transceiver
General Description
The TH8056 is a physical layer device for a single wire data link capable of operating with various CSMA/CR protocols
such as the Bosch Controller Area Network (CAN) version 2.0. This serial data link network is intended for use in
applications where a high data rate is not required and a lower data rate can achieve cost reductions in both the physical
media components and the microprocessor and/or dedicated logic devices that use the network.
The network shall be able to operate in either the normal data rate mode or the high-speed data download mode for
assembly line and service data transfer operations. The high-speed mode is only intended to be operational when the
bus is attached to an off-board service node. This node shall provide temporary bus electrical loads which facilitate
higher speed operation.
The bit rate for normal communications is typically 33.33kbit/s, for high-speed transmissions as described above a typical
bit rate of 83.33kbit/s is recommended. The TH8056 is designed in accordance with the Single Wire CAN Physical Layer
Specification GMW3089 V2.4 and supports many additional features like under-voltage lock-out, time-out for faulty
blocked
input signals, output blanking time in case of bus ringing and a very low sleep mode current.
