There are three ways to wake-up the TPIC1021 from Low Power Mode.
- Remote wake-up via recessive (high) to dominant (low) state transition on LIN Bus where dominant bus state of 50% threshold is detected. The dominant state must be held for tLINBUS filter time (to eliminate false wake ups from disturbances on the LIN Bus).
- Local wake-up via falling edge on NWake pin which is held low for filter time tNWake (to eliminate false wake ups from disturbances on NWake).
- Local wake-up via EN being set high
