  • Programmable low battery detector
    Patent number: 6373256
    Abstract: A low battery detect circuit with digitally programmable detect levels. The programmable low battery detect circuit includes a comparator that compares a stable reference voltage against a battery-supplied voltage as divided down by a digitally programmable resistive divider chain. By programmably varying the resistance of the divider chain, the low battery detect threshold level can be varied depending on the requirements of the application.
