Abstract
A circuit includes a fixed voltage drop circuit, a delay circuit, and a buffer. The delay circuit 13 coupled to the fixed voltage drop circuit, and the buffer 13 coupled to the delay circuit. The buffer has an activation voltage and is adapted to activate when the output of the delay circuit is less than the activation voltage. A method for detecting the loss of a power supply voltage includes coupling the power supply to a fixed voltage drop element to provide a first voltage at an output of the fixed voltage drop element. The first voltage is delayed to provide a second voltage, and the second voltage is provided to a buffer having an activation voltage. A reset signal is asserted at an output of the buffer when the second voltage is less than the activation voltage.
