NGD4300DDJ

Overview

The NGD4300DDJ is a half-bridge gate driver manufactured by Nexperia, designed for driving high-side and low-side N-channel MOSFETs in synchronous buck or half-bridge configurations. It operates within an 8 V to 17 V supply range and delivers a peak source current of 4 A and a peak sink current of 5 A. The device features non-inverting logic compatible with TTL and CMOS inputs down to 2.5 V. Key electrical parameters include a rise time of 4 ns and a fall time of 3.5 ns under 1,000 pF load conditions. It utilizes an HSO8 surface-mount package and supports operation across a temperature range of -40°C to +125°C.

Feature Summary

• Provides robust gate drive capability with 4 A peak source and 5 A peak sink currents for efficient switching of power MOSFETs.
• Features integrated bootstrap diode allowing high-side operation up to 120 V rail voltage without external components.
• Ensures precise timing control through excellent propagation delay matching between high-side and low-side outputs.

Applications

• Synchronous buck converters
• Half-bridge power configurations
• Current feedback push-pull converters

Procurement Notes

Verify the specific suffix 'J' against the manufacturer's official datasheet to confirm it denotes the correct tape-and-reel packaging format and quantity. Ensure the ordering part number matches the exact pinout and thermal characteristics required for your PCB layout. Cross-reference the RoHS compliance status and any automotive qualification markings if applicable to your production requirements.

Selection Notes

Select this component when designing circuits requiring independent high-side and low-side drive signals with tight delay matching. It is suitable for applications needing fast switching speeds and high current drive capabilities. Consider the HSO8 package constraints and ensure adequate thermal management for the operating environment.

Part Context

This device belongs to the Nexperia NGD4300 series of dual MOSFET gate drivers. The series is engineered for high-performance power management applications, offering a balance of speed, efficiency, and integration. The NGD4300DDJ variant specifically utilizes the HSO8 package, providing a compact solution for space-constrained designs while maintaining the series' core electrical performance specifications.

Replacement Considerations

Direct substitutes within the same family include NGD4300DJ (SO-8 package) and NGD4300GCJ (HWSON8 package). Verify that the alternative package type fits your board footprint and that the electrical parameters remain identical for your application needs.

FAQ

What is the maximum voltage rating for the high-side driver?

The high-side driver can operate with floating voltages up to 120 V relative to the ground reference.

Does the device support shutdown functionality?

No, the NGD4300DDJ does not include a dedicated shutdown pin; it relies on input signal control and UVLO for disabling outputs.
