Abstract
Automatic and robust anti-shoot-through glitch-free operation of half-bridge control pre-driver and power stage circuits have been achieved by using multiple feedback control signals. These feedback signals are taken both from the gates of power devices on high side and low sides and from the gates of one or more devices on both high side and low side that enable power device ON state. No duty cycle limitation is required of the input signal. The control logic uses NAND/NOR RS latches. The solution disclosed can readily be scaled to higher order of feedback loops providing even greater level of robustness.
