Features
Intelligent Drivers
and Actuators
Conforms to LIN Protocol Specification Rev. 1.3, 2.0
and SAE J2602
RF & RFID
The TH8082 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
uses the network.
• Compatible to LIN Specification Version 1.3 and 2.0
• Compatible to ISO9141 functions
• Operating voltage VS = 6 to 18 V
• Very low current consumption of typ. 7µA in sleep mode
Hall ICs
• Baud rate up to 20 kBaud
• Remote wake up via BUS traffic
• High signal symmetry for use in RC – based slave nodes
• Slew rate control for good EME behavior
• High EMI immunity
CMOS Imaging
• Control output for voltage regulator with low on resistance
for switchable master termination
• Fully integrated receiver filter
• High impedance BUS pin in case of loss of ground or
under-voltage condition
• BUS short to ground protection
Silicon MEMS
• BUS terminals proof against short-circuits and automotive
transients
• Automotive Temperature Range of –40°C to 125°C
• Thermal overload protection
• ±4kV ESD protection
• Small SOIC8 package
IR Temperature
• Load dump protection (40V)
