Melexis' 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 the physical media components and the microprocessor and/or dedicated logic devices that use the network.
Features
- Fully compatible with GMW3089 V 2.4 and J2411 single wire CAN specification for Class B in-vehicle communications
- 30 µA typical power consumption in sleep mode independent from CAN voltage range
- Operating voltage range 5 V to 26.5 V
- Up to 40 kbps bus speed
- Up to 100 kbps high-speed transmission mode
- ESD protection of 4 kV on CAN pin (2 kV on any other pin)
- Under voltage lockout
- Bus dominant time-out feature
- Thermal overload and short circuit protection
Applications
- Logic inputs compatible with 3.3 V and 5 V 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. 20 µA at 26.5 V and 125°C)
- Protection against load dump, jump start
- 14-pin thermally enhanced and 8-pin SOIC package
