NCV51511中文资料100V 高频率，高压侧和低压侧门极驱动器数据手册ONSEMI规格书

描述 Description

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 driver
IC 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-side
and low-side of N-Channel MOSFETs in a half bridge or synchronous
buck configuration. The floating high-side driver is capable of operating
with supply voltages of up to 80 V. In the dual gate driver, the high side
and low side each have independent inputs which allow maximum
flexibility of input control signals in the application. The PWM input
signal (high level) can be 3.3 V, 5 V or up to VDD logic input to cover all
possible applications.
