Abstract
Systems, structures, packages, circuits, and methods provide high-side gate driver circuits configured to control operation of high-side power (switching) transistors without use of external bootstrap capacitors. A high-side driver can include three sections, including a pull-up section, first pull-down section, and a second pull-down or Miller clamp section. The gate drivers can include a charge pump circuit and can avoid use of bootstrap capacitors and related circuitry. Partitioned gate drivers can include an individual pull-up section, an individual first pull-down section, and an individual second pull-down section for each of multiple high-side power transistors.
