Sleep Mode is the low-power mode of LIN transceivers. This mode is used to save power when the LIN transceiver is not needed in any part of the system. The mode is typically entered by putting a logic low on the Enable pin (if there is one) of the device. The name Sleep Mode implies the device is in a less functional state, but is still able to monitor the LIN bus for any wakeup signals (explained further in Section 5.2).
In Sleep mode, the LIN driver is disabled and the internal LIN bus termination is switched off to minimize current draw if the LIN bus is shorted to ground for any reason. A low-power receiver is enabled and the normal receiver function is disabled, and EN input is still active.
