LIN system chip set to cash in on new
specs
The TH8062 is the first of a new generation of LIN system ICs from Melexis and is pin compatible with the company's existing TH8061.
The LINbus (Local Interconnect Network) is set to continue its success in automotive and industrial applications with the release of LIN version 2.0 and the release of the SAE2602 networking specification This robust, cost effective communication scheme enables many basic networking functions in subsystems previously considered to be uneconomical for smart actuators and controls

Melexis has developed a new programmable single chip CMOS LED driver for high-power (1W) LEDs.
PLL-based transmitters shrink into MLPs
A new range of low-power radio transmitter chips covering frequencies from 300 to 930MHz are the first devices of their type to be produced in the very tiny micro leadframe package.
The new TH8062 from Melexis extends its successful LIN transceiver and system chip product line for the simple and effective development of LIN slaves.
This IC combines a physical layer LIN transceiver according to LIN 2.0 as well as SAEJ2602 with a 5V voltage regulator with reset output for the connected microcontroller.
This combination reduces the LIN system costs and makes it possible to develop simple but powerful and cheap LIN slaves with a direct connection to a 12V board power network.

Integrated pressure sensors for automotive use
A new family of fully integrated and programmable pressure sensor solutions has been introduced by Melexis, designed for harsh automotive duty.
The new device is optimised in accordance with the increased EMC requirements for single wire bus systems.
The TH8062 is the first of a new generation of LIN system ICs from Melexis and is pin compatible with the company's existing TH8061.
The Melexis TH8062 is produced using 0.8um HV-CMOS technology and optimised for minimal current consumption as well as excellent EMC behaviour.
The current consumption in standby mode is typically 15uA.
Integral standby management assures that the TH8062 can "wake up" from the LINbus itself or directly from a connected microcontroller or other external source.
This IC also generates a reset output signal to minimise the external circuitry of the microcontroller.
The power on reset time is programmable from 4 to 30ms.
The integrated voltage regulator generates output voltage of 5V +/-2% with a maximum load current of 70mA.
For self protection the IC is equipped with an integrated load current limiter, overtemperature shutdown and 40V load dump protection.
The EMC behaviour of LINbus ICs is critical in automotive applications.
The TH8062 design exhibits remarkable robustness when subjected to high frequency disturbances.
The IC also has very low levels of electromagnetic emissions to further simplify the design challenges of networked communication in hostile automotive environments.
For the data transmission according J2602 a special low slew mode is available.
With the help of this mode the emission can be further reduced if only half of the LINbus bandwidth is used.
The TH8062 is qualified in accordance to AECQ100 and is RoHS compatible.
It can be soldered up to 260C according to JEDEC 020C.
Samples are available in SOIC8 packages.
