Automotive ICs
Single LIN Transceiver
TH8080
Bus ICs
Because of its very low current consumption in
recessive state TH8080 is suitable for ECU applications
that have stringent standby current requirements,
whereby no sleep/wake up control from the
microprocessor is necessary.
Intelligent Drivers
and Actuators
Conform to LIN Protocol Specification Rev. 1.3, 2.0 and
SAE J2602
RF & RFID
The TH8080 is a physical layer device for a single wire
data link. It is capable of operating in applications
where no high data rates are required and lower data
rates can generate cost reductions both in the physical
media components and in the microprocessor which use
the network.
