Abstract
A half bridge circuit is disclosed. The circuit includes low side and high side power switches selectively conductive according to one or more control signals. The circuit also includes a low side power switch driver, configured to control the conductivity state of the low side power switch, and a high side power switch driver, configured to control the conductivity state of the high side power switch. The circuit also includes a controller configured to generate the one or more control signals, a high side slew detect circuit configured to prevent the high side power switch driver from causing the high side power switch to be conductive while the voltage at the switch node is increasing, and a low side slew detect circuit configured to prevent the low side power switch driver from causing the low side power switch to be conductive while the voltage at the switch node is decreasing.
