Abstract
Described embodiments include a gate drive circuit with a first transistor coupled between an input voltage terminal and a switching terminal, and having a first control terminal. A second transistor is coupled between the switching terminal and ground, and has a second control terminal. A first driver circuit has a first driver output coupled to the first control terminal, a first positive supply input coupled to a bootstrap voltage terminal, and a first negative supply input coupled to the switching terminal. A second driver circuit has a second driver output coupled to the second control terminal, a second positive supply input coupled to a driver supply, and a first negative supply input coupled to ground. An active clamp circuit is coupled between the driver supply and ground, and prevents a voltage between the driver supply and ground from exceeding a threshold voltage.
