Abstract: A circuit includes a half-bridge circuit is configured to provide a switching voltage responsive to respective high-side and low-side drive signals. High-side slew control circuitry is configured to provide a high-side slew-compensated control signal responsive to a high-side enable signal and a slew current signal representative of a slew rate at a switching output. A high-side driver is configured to provide the high-side drive signal responsive to the high-side slew-compensated control signal. Low-side slew control circuitry is configured to provide a low-side slew-compensated drive signal responsive to a low-side enable signal and the slew current signal. A low-side driver is configured to provide the low-side drive signal responsive to the low-side slew-compensated control signal. A capacitor is coupled between the high-side and low-side slew control circuitry and is configured to convert the slew rate to the slew current signal.
