UCC27311A/UCC27311A-Q1 Half-Bridge Drivers

Texas Instruments UCC27311A/UCC27311A-Q1 Half-Bridge Drivers are robust gate drivers designed to drive two N-channel MOSFETs in a half-bridge or synchronous buck configuration with an absolute maximum bootstrap voltage of 120V. Its 3.7A peak source and 4.5A peak sink current capability allow the UCC27311A/UCC27311A-Q1 to drive large power MOSFETs with minimized switching losses during the transition through the Miller Plateau. The switching node (HS pin) can handle the negative transient voltage, protecting the high-side channel from inherent negative voltages caused by stray capacitance and parasitic inductance.
