Abstract

See full text

A voltage divider circuit is provided that automatically and dynamically adjusts its voltage divider chains as a supply voltage changes. The voltage divider circuit includes a plurality of voltage divider branches having different divider factors to divide the supply voltage and obtain a divided supply voltage. Additionally, a control circuit is coupled to the plurality of voltage divider branches and adapted to automatically monitor the supply voltage and dynamically select a voltage divider branch from among the plurality of voltage divider branches to maintain a selected divided supply voltage within a pre-determined voltage range.
