Abstract
A controller for a half-bridge power circuit includes a measurement circuit, a controller circuit, a high-side delay circuit, and a low-side delay circuit. The measurement circuit connects to the half-bridge node, measures the half-bridge voltage, and generates a multi-bit status signal indicative of the measured half-bridge voltage. The controller circuit connects to the measurement circuit, and receives the status signal therefrom. The controller circuit generates at least a delay control signal based on the status signal. The high-side delay circuit connects to the controller circuit to receive the delay control signal. The high-side delay circuit provides a high-side control signal in response to the delay control signal, to switch on/off the high-side switch. The low-side delay circuit connects to the controller circuit to receive the delay control signal. The low-side delay circuit provides a low-side control signal in response to the delay control signal, to switch on/off the low-side switch.
