Nexperia NGD4300 Half-bridge gate drivers

The new series of high-performance gate driver ICs is designed for driving both high-side and low-side N-channel MOSFETs in a synchronous buck or half-bridge configuration. These devices deliver high current output and excellent dynamic performance, boosting efficiency and robustness in applications. The automotive-qualified NGD4300-Q100 is ideal for electronic power steering and power converters, while the NGD4300 has been designed for use with DC-DC converters in consumer devices, servers and telecommunications equipment as well as for micro-inverters used in various industrial applications. With integrated bootstrap circuit and components, the NGD4300 simplifies system design by removing dedicate high side driving circuit. To achieve high robustness in power conversion and motor driving applications, NGD4300 used SOI process to extend negative voltage tolerance of HS pin to -5VDC, this significantly reduces the risk to damage the IC caused by system parasitic component and unexpected spikes across all working conditions. NGD4300 also has 4ns and 3ns typical rise and fall time to contribute to high driving efficiency, and 13ns typical delay and 1ns delay matching to support high frequency and fast system control.
