Abstract
Embodiments of the present disclosure include a power management unit for controlling power in a microcontroller. The unit causes a first voltage to be provided in an active mode. In a sleep mode, the unit determines whether a supply voltage is less than an upper reference voltage and, if so, cause a second voltage greater than the first voltage to be provided. If not, the unit inhibits operation of voltage regulation of power supplied to the microcontroller. After inhibition of operation of voltage regulation, the unit determines whether the supply voltage has fallen to a lower reference voltage and, if so, applies the second voltage to the microcontroller.
