Abstract

Adaptive gate drivers and related methods and systems are disclosed. An example gate driver system includes a comparator, a latch having first and second inputs and outputs, the first input coupled to the comparator, a timer having an input and an output, the input coupled to the first output of the latch, the output coupled to the second input of the latch, control logic having an input and first and second outputs, the input coupled to the second output of the latch, first and second transistors having a gate, a first buffer having an input and an output, the input coupled to the first output of the control logic, the output coupled to the gate of the first transistor, and a second buffer having an input and an output, the input coupled to the second output of the control logic, the output coupled to the gate of the second transistor.

Dependent claims

A gate driver system comprising:

a comparator having an output;
a latch having a first input, a second input, a first output, and a second output, the first input of the latch coupled to the output of the comparator;
a timer having an input and an output, the input of the timer coupled to the first output of the latch, the output of the timer coupled to the second input of the latch;
