2. 5VSTBY or 5VSTB is the Ultimate Chip Enable. This supply has to be up first to ensure gates are in known state.
3. 12 V and 5 V supplies can ramp in either order.
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 rises.
6. MCH SS is completed, then SS pin is released from MCH. SS pin is shorted to ground. S0 Mode.
7. S3 MODE BUF_CUT = H.
8. VTT and MCH will be turned off.
9. 12 V and 5 V ramps to 0 V.
10.Standard S3 Mode.
11.12 V and 5 V ramp back to regulation.
12.BUF_CUT goes LOW.
13.12 V UVLO = L and BUF_CUT = L. MCH ramps with SS pin, timing is 0.8 * C
SS
/ 8 (sec). VTT rises.
14.S0 Mode.
15.Prepare S5 Mode BUF_CUT = L, and 12VUVLO = H or 5VUVLO = H.
16.DDQ, VTT, and MCH Turned OFF.
17.S5 Mode.
