Patent ID: 7457137

Claim:
An output control for an electrical circuit having a control loop and a main output signal, comprising: a sense input connected to receive a signal derived from the main output signal; a sense circuit constructed to establish a first threshold of a difference between said main output signal and a reference signal, said sense circuit constructed to establish a second threshold of a difference between said reference signal and said signal derived from the main output signal, said sense circuit having a sense output for a sense output signal; and a connection from said sense output to the control loop, wherein said sense circuit includes: a first comparator connected to compare said reference signal to said signal derived from the main output signal; and a second comparator connected to compare the main output signal to said reference signal, and wherein said reference signal is connected to said first comparator through a first voltage divider, and said main output signal is connected to said second comparator through a second voltage divider.
