2. 5VSTBY or 5VSTB is the ultimate chip enable, SLP_S5 and SLP_S3 go HIGH. This supply has to be up first to
ensure gates are in known state.
3. 12 V supply ramp.
4. DDQ will ramp with the tracking of SS pin, timing is 1.2 * C
SS
/ 4 (sec).
5. DDQ SS is completed, then SS pin is released from DDQ. SS pin is shorted to ground.
5. MCH ramps with the tracking of SS pin ramp, timing is 0.8 * C
SS
/ 8 (sec). VTT start up with current limit.
6. MCH SS is completed, then SS pin is released from MCH, SS pin is shorted to ground. S0 Mode.
7. S3 MODE SLP_S3 = L.
8. VTT and MCH will be turned off.
9. 12 V ramps to 0 V.
10.Standard S3 State.
11.SLP_S3 goes HIGH.
12.12 V ramps back to regulation.
13.12 V UVLO = L and SLP_S3 = H. MCH ramps with SS pin, timing is 0.8 * C
SS
/ 8 (sec). VTT rises.
14.S0 Mode.
15.S5 Mode SLP_S5 = L.
16.DDQ, VTT and MCH Turned OFF.
17.S5 Mode.
