5.1 POWER OFF MODE
(Submit Feedback)The ATA6847/ATA6847L is in Power OFF mode as long as the supply voltage of the device (VVS) is lower than the Power OFF Detection Voltage Threshold (VVS_PWROFF).
- The integrated LIN transceiver is in LIN Unpowered mode (see LIN Transceiver).
- The watchdog is inactive.
- The LDO(s) is/are inactive.
As soon as VVS rises above the Power ON Detection Threshold (VVS_PWRON), the device starts transitioning to MCU Reset mode. The device is reset, initialized and the VDDx LDOs are enabled, see Figure 5-3, "Mode Switching During Power ON Start and Power OFF (ATA6847-5050, RSTLVL = ‘1’)".
