Atmel’s ATA6663 and ATA6664 are stand-alone LIN bus transceiver ICs, while the ATA6628/29/30/31 LIN transceivers are system basis chips (SBCs). When compared to a stand-alone LIN transceiver, SBCs are more integrated to include a voltage regulator, a Watchdog Timer (WDT), and high precise voltage divider for supply voltage measurements. The devices’ low-power management also enables mixed-supplied LIN bus systems and short circuit-to-ground at the LIN bus with a lower power consumption.
These new LIN devices are designed with Atmel’s high-voltage BCD-on-SOI (SMART-I.S.(TM)) process and optimized for operations up to 40V for applications in harsh environments. Combined with the industry’s leading EMC robustness (EMC test and conformance test LIN2.1, Europe, and SAE J2602-2, US), customers can benefit from lower bill of material as well as lower software costs. The excellent ESD protection (exceeding 6 kV) is beneficial for designing robust electronic units for the harsh automotive environment.
