TH8056KDCA Datasheet

Interface - Drivers,Receivers, Transceivers


The TH8056KDCA 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 TH8056KDCA 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. TH8056KDCA Features • 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
