100V High-Frequency, High Side and Low Side Gate Driver

The NCV51511 is high side and low side gate-drive IC designed for high voltage, high-speed, driving MOSFETs operating up to 80 V.The NCV51511 integrates a driver IC and a bootstrap diode. The driverIC features low delay time and matched PWM input propagation delays,which further enhance the performance of the part.The high speed dual gate driver are designed to drive both the high-sideand low-side of N-Channel MOSFETs in a half bridge or synchronousbuck configuration. The floating high-side driver is capable of operatingwith supply voltages of up to 80 V. In the dual gate driver, the high sideand low side each have independent inputs which allow maximumflexibility of input control signals in the application. The PWM inputsignal (high level) can be 3.3 V, 5 V or up to VDD logic input to cover allpossible applications.
