A brown out detector includes a first resistive element connected to a first voltage and a first node. A capacitor is connected to the first node and a second voltage. The detector also includes a second transistor and a third transistor. The second transistor has a drain connected to a second node, a source connected to the first node, and a gate connected to the first voltage. The third transistor has a source connected to the second voltage and the capacitor, a drain connected to the second node, and a gate connected to the first voltage. The detector also includes a latch having an input connected to the second node and a detector output, which generates a reset signal when the first voltage is less than a detection threshold voltage.
