Adaptive gate drivers and related methods and systems

Abstract:

In a gate driver, a comparator input is adapted to be coupled through a resistor and a diode to a first transistor. A latch input is coupled to a comparator output. A second transistor has a first control terminal and a first output terminal. The first output terminal is adapted to be coupled to a control terminal of the first transistor. A third transistor is smaller than the second transistor. The third transistor has a second control terminal and a second output terminal. The second output terminal is adapted to be coupled to the control terminal of the first transistor. Control logic has a logic input and first and second logic outputs. The logic input is coupled to a latch output. The first logic output is coupled to the first control terminal. The second logic output is coupled to the second control terminal.
