METHOD FOR DETECTING A CURRENT AND COMPENSATING FOR AN OFFSET VOLTAGE AND CIRCUIT

摘要

PURPOSE: A method for detecting a current and compensating for an offset voltage and a circuit is provided to set turn-off threshold voltage by detecting zero current conditions and initializing offset. CONSTITUTION: In a method for detecting a current and compensating for an offset voltage and a circuit, a first comparator(10) comprises first and second input terminals and an output terminal. A second comparator(20) comprises a first to third input terminal and an output terminal. The first terminal of the first comparator is connected to the second terminal of the second comparator. A first logic circuit comprises first and the second input terminal and an output terminal. A driver circuit(46) comprises an input terminal and an output terminal.
