ATA663232/55 LIN System Basis Chip Including LIN Transceiver, Voltage Regulator and Wake-Input
ATA663232/55 is designed to handle the low speed 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 guarantee minimized current consumption even in the case of a floating or a short circuited LIN bus.
The voltage regulator is a fully integrated low drop voltage regulator, with 5V/3.3V 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 170μA (without load), even if the supply voltage is below the regulator’s nominal output voltage.
