Claim Text:
1. A system capable of an automatic and robust anti-shoot-through glitch-free operation of half-bridge control pre-driver and power stage circuits using at least two feedback loops from each branch of the half-bridge, comprising: one input port receiving an input signal; one output port; a high-side branch and a low-side branch arranged in parallel, wherein both branches are connected to the input port, each branch comprising: wherein both power transistors are connected in series between VDD voltage and ground, wherein a source of the high side power transistor is connected to VDD voltage, a drain of the high side power transistor is connected to a drain of the low side power transistor, the source of the low side power transistor is connected to ground, wherein the drains of both power transistors are connected to the output port, wherein only the drains of the power transistors provide input to the output port, and wherein two or more feedback loops from each branch are implemented from each branch to the logic control blocks of the opposite branch in order to be capable of preventing cross-conduction between both power transistors of the low side and of the high side.
