專利摘要(中)
The present invention discloses a power booting sequence control system and the control method thereof, which optimizes a power booting sequence of a plurality of power switches in an integrated circuit. An initial module initializes a target charge value, a preset current budget and a plurality of time intervals. A current lookup module obtains a booting current across a power switch from a built-in current lookup table. A first computing unit and a second computing unit compute a first and a second power switch numbers respectively. A processing module selects the small number of the first and the second power switch number to get a maximum number of power booting switches under the time intervals, and opens the maximum number of the power booting switches. Therefore, the system keeps the in-rush current value under the preset current budget and speeds up the ramp-up time in a power booting state.
