The TH8082 is a physical layer device for a single wire data link capable of operating in applications where high data rate is not required and a lower data rate can achieve cost reductions in both the physical media components and in the microprocessor which use the network. The TH8082 is designed in accordance to the physical layer definition of the LIN Protocol Specification, Rev. 1.3.The IC furthermore can be used in ISO9141 systems.
Because of the very low current consumption of the TH8082 in the sleep mode it’s suitable for ECU applications with hard standby current requirements. This mode allows a shutdown of the whole application. The included wake-up function detects incoming dominant bus messages and enables the voltage regulator.
