MICROCHIP ATA663231-GBQW

The ATA663201/03/31/54 device family includes two basic products: a LIN system basis chip (SBC) and a low-drop voltage regulator with compatible footprints. The ATA663231/54 (SBC) is a fully-integrated LIN transceiver, designed according to the LIN specification 2.0, 2.1, 2.2, 2.2A, ISO 17987-4 and SAEJ2602-2, with a low-drop voltage regulator (3.3V/ 5V/85 mA). The combination of voltage regulator and bus transceiver makes it possible to develop simple but powerful nodes in LIN bus systems. The ATA663231/54 is designed to handle the lowspeed data communication in vehicles (for example, in convenience electronics). Improved slope control at the LIN driver ensures secure data communication up to 20 Kbaud. The bus output is designed to withstand high voltage. Sleep mode and Silent mode ensure minimized current consumption even in the case of a floating or a short-circuited LIN bus. The ATA663201/03 (voltage regulator) is a fully integrated low-drop voltage regulator, with 3.3V/5V output voltage and 85 mA current capability. It is especially designed for the automotive environment. A key feature is that the current consumption is always below 170 μA (without load), even if the supply voltage is below the regulator’s nominal output voltage.
