Melexis Debuts TH8060 and TH8061 Automotive ICs

September 17, 2001 by Jeff Shepard

Melexis GmbH (Germany) announced the TH8060 and TH8061 automotive ICs, which provide LIN bus architects with high-integration slave transceiver ICs that combine both a LIN transceiver with an LDO voltage regulator. This reduces component count and makes it possible for designers to develop simple, powerful, and less expensive LIN bus slave nodes that can be connected directly to the power line. Both conform to LIN Specification 1.2.

The devices are optimized for low-current consumption. They typically draw only 25µA on standby. With an integrated standby management feature, the transceiver can wake up with either a signal on the LIN bus or directly from the connected microcontroller. They generate a reset output signal with the integrated reset unit to simplify the external circuitry of the micro-controller. Configurable reset time is 15ms or 100ms, and reset threshold voltage is 3.15V or 4.65V. The data rate for both transceivers is as high as 20kbaud.

The integrated voltage regulator delivers an output voltage of 5V (±2 percent). The TH8060 has an output current of 100mA, and the TH8061 of 50mA. Both transceivers have output current limiting, over-temperature shutdown and 40V load-dump protection.

The TH8060, in an SOIC16, is quoted at about $2.50, and the TH8061, in SOIC8, is priced at about $1.70, both in 1,000-piece quantities.
