ATAB663211A-V1.2 Microchip

ATA663211 LIN Transceiver DATASHEET Features Supply voltage up to 40V Operating voltage V = 5V to 28V S Very low supply current Sleep mode: typically 9A Fail-safe mode: typically 80A Normal mode: typically 250A Fully compatible with 3.3V and 5V devices LIN physical layer according to LIN 2.0, 2.1, 2.2, 2.2A and SAEJ2602-2 Wake-up capability via LIN bus (100s dominant) External wake-up via WKin pin (100s low level) INH output to control an external voltage regulator or to switch the master pull-up Wake-up source recognition TXD time-out timer Bus pin is over-temperature and short-circuit protected vs. GND and battery Advanced EMC and ESD performance Fulfills the OEM Hardware Requirements for LIN in Automotive Applications Rev.1.3 Interference and damage protection according to ISO7637 Qualified according to AEC-Q100 Package: SO8, DFN8 with wettable flanks (Moisture Sensitivity Level 1) 9359D-AUTO-10/161. Description The Atmel ATA663211 is a fully integrated LIN transceiver designed in compliance with the LIN specification 2.0, 2.1, 2.2, 2.2A and SAEJ2602-2. It interfaces the LIN protocol handler and the physical layer. The device is designed to handle the low-speed data communication in vehicles, for example, in convenience electronics. Improved slope control at the LIN bus ensures data communication up to 20Kbaud. Sleep mode guarantees minimal current consumption even in the case of a floating bus line or a short circuit on the LIN bus to GND. Figure 1-1.
