Abstract
A half-bridge circuit comprises a high supply contact and a low supply contact. A half-bridge output contact is connectable to drive a load and has a high-side between the high supply contact and the half-bridge output contact and a low-side between the half-bridge output contact and the low supply contact. A high-side bidirectional vertical power transistor at the high-side has a source connected to the high supply contact, and a low-side bidirectional vertical power transistor at the low-side, transistor has a source connected to the low supply contact. The high-side bidirectional vertical power transistor and low-side bidirectional vertical power transistor are connected in cascode and share a common drain connected to the half-bridge output contact, and are controllable to alternatingly allow a current flow from the high supply contact to the half-bridge output contact or from the half-bridge output contact to the low supply contact.
