Abstract
An integrated half-bridge driver circuit for driving a half-bridge output stage having high-side and low-side power transistors coupled together at a high-voltage output terminal includes a low-voltage control circuit and a floating well within the integrated circuit which has a timing circuit for controlling the activation of the high-side power transistor. The driver circuit further includes a high-voltage interface circuit for coupling a control signal from the low-voltage control circuit to the timing circuit within the floating well. In this manner, an integrated half-bridge driver circuit is obtained which is capable of operating at high frequencies due to the relatively low power dissipation in the control and timing circuitry.
