ABSTRACT:
A single sleep mode controller which ensures that there is at least a corresponding minimum voltage level across capacitors when the corresponding regulators are turned off. In an embodiment, the sleep mode controller uses a single comparator which compares the voltages across capacitors in a time division multiplexed (TDM) manner, and initiates the charging operation for the capacitor if the voltage level falls below a corresponding minimum voltage level. The sleep mode controller continues the charging operation until the voltage level exceeds a corresponding upper threshold value. Due to the use of the single controller, power and/or space savings may be attained.
