  • Method and apparatus for band-gap based power-on-reset including fast, low power and accurate brownout detection
    Patent number: 10454468
    Abstract: A power-on reset (POR) circuit with an auxiliary control circuit and an enhanced resistor ladder for brownouts circuit detectors in low power applications includes a power-up detector circuit for detecting power supply ramp-up while charging; a brownout detector circuit for sensing power supply falling down; a set-reset (SR) latch to generate a power-on-reset (POR) signal; a start-up network; and an internal band-gap voltage reference circuit, wherein the internal band-gap voltage reference circuit is configured to be started by the start-up network to serve as a reference for the power-up detector circuit.
