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.

Features

❐ Fully compliant to GMW3089 V2.4 and J2411 Single Wire CAN specification for Class B in-vehicle communications

❐ Only 60 µA worst case sleep mode current independent from CAN voltage range

❐ Operating voltage range 5V to 26.5V

❐ Up to 40 kbps bus speed

❐ Up to 100 kbps high-speed transmission mode

❐ Logic inputs compatible with 3.3V and 5V supply systems

❐ Control pin for external voltage regulators

❐ Low RFI due to output wave shaping in normal and high voltage wake up mode

❐ Fully integrated receiver filter

❐ Bus terminals proof against short-circuits and transients in automotive environment

❐ Loss of ground protection, very low leakage current (typ. 20µA at 26.5V and 125°C)

❐ Protection against load dump, jump start

❐ Thermal overload and short circuit protection

❐ Under voltage lockout

❐ Bus dominant time-out feature

❐ Pb-Free 14-pin thermally enhanced and 8-pin SOIC package
