The Microchip's ATA663331 is a new generation of system basis chip with a fully integrated LIN transceiver, designed in compliance with LIN specifications 2.0, 2.1, 2.2, 2.2A and SAEJ2602-2, a low-drop voltage regulator (3.3V/85mA), two low-side drivers, and one high-side driver. This combination makes it possible to develop simple, but powerful, slave nodes in LIN bus systems. Microchip ATA663331 is designed to handle low-speed data communication in vehicles (such as in convenience electronics). Improved slope control at the LIN driver ensures secure data communication up to 20kBaud. The bus output is designed to withstand high voltage. Sleep mode and silent mode guarantee minimized current consumption even in the case of a floating or short-circuited LIN bus.

The voltage regulator is a fully integrated low-drop voltage regulator, with 3.3V output voltage and 85mA current capability. It is especially designed for the automotive environment. A key feature is that the current consumption is always below 170µA (without load), even if the supply voltage is below the regulator's nominal output voltage.
