  "textContent": "A brown-out detection apparatus including a voltage sensing circuit, a first circuit, and a second circuit. The voltage sensing circuit senses an input AC voltage having a first nominal input voltage value or a second nominal input voltage value. The voltage sensing circuit includes an output outputting a reference DC voltage proportional said input AC voltage. The first circuit is responsive to said output of said voltage sensing circuit. The first circuit includes a first output outputting a first voltage value when said input AC voltage is below a threshold voltage level and a second voltage value when said input AC voltage is above said threshold level. The second circuit is responsive to said first output. The second circuit includes a second output outputting a second control signal indicative of a brown-out condition of said input AC voltage.",
