Automotive ICs Single Wire CAN Transceiver TH8056 Bus ICs Hall ICs Features Intelligent Drivers and Actuators 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.x 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. RF & RFID 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. • Fully compatible with GMW3089 V2.x and J2411 Single Wire CAN specification • 30 µA typical power consumption in sleep mode • Up to 40 kbps bus speed • Up to 100 kbps high-speed mode • Logic inputs compatible with 3.3V and 5V CMOS Imaging • Operating voltage range 5V to 27V • Control pin for external voltage regulators • 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 27V and 125°C) • Protection against load dump, jump start Silicon MEMS • Low RFI due to output wave shaping in normal and high voltage wake up mode • Thermal overload and short circuit protection • Under voltage lockout • Bus dominant time-out feature • 14-pin thermally enhanced and 8-pin SOIC package • Available as lead free and RoHS compliant IR Temperature • ESD protection of 4 kV on CAN pin (2kV on any other pin) Automotive ICs Application Circuitry VBAT VBAT_ECU 4,7uF Additional Loads Voltage regulator RF & RFID VBAT +5V ECU connector to Single Wire CAN Bus 100nF Intelligent Drivers and Actuators 2.7k VBAT INH 9 CAN controller RxD MODE0 Bus ICs MODE1 TxD 100pF 5 47µH 4 7 2 TH8056 3 1 CANH 1k 6.49kOhm 6 47pF LOAD ESD Protection TPSMA16A or MMBZ27VCLT1 or equivalent - if needed 1,7,8,14 GND Applications Hall ICs • All Applications which require a Single Wire CAN Interface • GM-LAN according to GMW3089 Rev 2.x • Usable for GMT-900, Epsilon-2 and Global-A platforms CMOS Imaging Pinout SOIC14, fused leadframe Silicon MEMS SOIC8 TxD 1 8 GND MODE0 2 7 CANH MODE1 3 6 LOAD RXD 4 5 VBAT TH8056 GND 1 14 GND TxD 2 13 N.C.
