Sleep mode is the power saving mode for the SN65HVDA100-Q1. Even with the extremely low current consumption in this mode, the SN65HVDA100-Q1 can still wake up from LIN bus through a wake-up signal, a low on NWake, or if EN is set high. The LIN bus and NWake are filtered to prevent false wake-up events. The wake-up events must be active for their respective time periods (t_LINBUS, t_NWake).

The sleep mode is entered by setting EN low.

While the device is in sleep mode, the following conditions exist:

• The LIN bus driver is disabled and the internal LIN bus termination is switched off (to minimize power loss if LIN is short circuited to ground). However, the weak current pullup is active to prevent false wake-up events in case an external connection to the LIN bus is lost.
• The normal receiver is disabled.
• INH is high impedance.
• EN input, NWake input, and the LIN wake-up receiver are active.
