Power management circuit for a digital cordless telephone.

摘要

A power management circuit for a battery-powered apparatus which is designed to sleep during predetermined periods when the apparatus is not in use, which has an oscillator that generates a clock signal therefor, and which has a battery monitoring subcircuit that indicates when a predetermined low battery power state is reached, includes subcircuitry that enables the oscillator to generate a clock signal, and subcircuitry responsive to an indication from the battery monitoring subcircuit that the predetermined low battery power state is reached, which subcircuitry suspends operation of the subcircuitry that enables the oscillator to generate a clock signal.
