The NGD4300DJ from Nexperia is a High-Performance Dual MOSFET Gate Driver that is designed to drive both high-side and low-side N-channel MOSFETs in a synchronous buck or a half-bridge configuration. It requires an input voltage of 8 - 17 V. This gate driver has input signals complying with both TTL and CMOS signaling at 2.5 V, 3.3 V, and 5 V. It has output signals with excellent propagation delay matching and achieves fast propagation times.
This gate driver has a peak source current of 4 A and a sink current of 5 A sink, thereby guaranteeing short rise and fall times even under high loads. It includes bootstrap supply voltage of up to 120 V using an integrated bootstrap diode. This low-power-consuming gate driver benefits from under-voltage protection for both low-side and high-side supplies. It is available in a surface-mount package that measures 5 x 4 x 1.75 mm and is ideal for current-fed, push-pull converters, two-switch forward power converters, class-d audio amplifiers and solid-state motor drive applications.
