NGD4300DD-Q100J

Overview

The NGD4300DD-Q100J is a dual MOSFET gate driver designed for synchronous buck and half-bridge configurations. It features peak pull currents of 4 A and sink currents of 5 A, supporting rail voltages up to 120 V with an integrated bootstrap diode. The device operates within a supply voltage range of 8 V to 17 V and accepts TTL/CMOS inputs compatible with 2.5 V, 3.3 V, and 5 V logic. It exhibits a typical propagation delay of 13 ns and excellent delay matching of 1 ns. Operating temperatures span from -40°C to +125°C in an SO8 package.

Feature Summary

• High-current output stage capable of driving high-side and low-side N-channel MOSFETs in demanding power applications
• Integrated bootstrap diode enables floating high-side drive operation at rail voltages up to 120 V
• Independent under-voltage lockout circuits protect outputs when driver supply falls below threshold levels
• Low-power internal regulator maintains signal path performance independent of IC supply voltage variations

Applications

• Synchronous buck converters
• Half-bridge configurations
• Current feedback push-pull converters
• Dual switch forward power converters
• Solid-state motor drives

Procurement Notes

Verify the specific suffix DD indicates the SO8 package variant when sourcing. Confirm AEC-Q100 Grade 1 qualification status aligns with automotive reliability requirements. Ensure input logic levels match system control signals, as the device supports 2.5 V, 3.3 V, and 5 V compatibility. Check thermal management needs given the 125°C maximum operating temperature rating.

Selection Notes

Select this component for designs requiring robust gate driving in high-voltage environments up to 120 V. The tight delay matching of 1 ns makes it suitable for applications where timing precision between high-side and low-side switches is critical. Consider the 4 A pull and 5 A sink capabilities for driving MOSFETs with significant gate charge requirements efficiently.
