Abstract:
A circuit includes a high-side switch and a low-side switch. A first inverter includes first and second discharge current paths activatable to sink first and second discharge currents, respectively, from the control terminal of the high-side switch. A second inverter includes first and second charge current paths activatable to source first and second charge currents to the control terminal of the low-side switch. A high-side sensing current path includes an intermediate high-side control node, and a low-side sensing current path includes an intermediate low-side control node. The second discharge current path is selectively enablable in response to a high-side detection signal at the intermediate high-side control node having a high logic value, and the second charge current path is selectively enablable in response to a low-side detection signal at the intermediate low-side control node having a low logic value.
