描述： The IR11682SPBF is a DUAL SmartRectifier? secondary-side Rectifier Driver IC designed to drive two N-channel power MOSFETs used as synchronous rectifiers in resonant converter applications. The IC can control one or more paralleled N MOSFETs to emulate the behaviour of Schottky diode rectifiers. The drain to source for each rectifier MOSFET voltage is sensed differentially to determine the level of the current and the power switch is turned ON and OFF in close proximity of the zero current transition. The anti shoot-through logic prevents both channels from turning on the power switches at the same time. The cycle-by-cycle MOT protection circuit can automatically detect no load condition and turn off gate driver output to avoid negative current flowing through the MOSFETs. Ruggedness and noise immunity are accomplished using an advanced blanking scheme and double-pulse suppression that allows reliable operation in fixed and variable frequency applications. . For synchronous rectification in resonant half bridge topologies . Anti-bounce logic and UVLO protection . Micropower start-up and ultra low quiescent current . 80ns Turn-OFF propagation delay . Wide Vcc operating range . Direct sensing for both synchronous rectifiers . Minimal component count . Simple design
