NGD4300GCJ

Overview

The NGD4300GCJ is a dual MOSFET gate driver manufactured by Nexperia, designed for high-side and low-side N-channel MOSFETs in synchronous buck or half-bridge configurations. It features a peak pull current of 4 A and a peak push current of 5 A. The device operates with a supply voltage range of 8 V to 17 V and supports floating high-side operation up to 120 V using an integrated bootstrap diode. Input signals compatible with 2.5 V, 3.3 V, and 5 V TTL/CMOS logic are accepted. Propagation delay is typically 13 ns with excellent matching of 1 ns between channels. Rise time is 4 ns and fall time is 3.5 ns under 1,000 pF load conditions. The component functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides robust driving capability for high-side and low-side N-channel MOSFETs in half-bridge and synchronous buck topologies
• Features independent undervoltage lockout circuits for both high-side and low-side outputs to prevent malfunction during power-up
• Includes an internal regulator that maintains consistent drive performance regardless of IC supply voltage variations
• Offers high ESD protection exceeding 2,000 V HBM and 1,000 V CDM standards

Applications

• Synchronous buck converters
• Half-bridge configurations
• Current feedback push-pull converters
• Dual-switch forward power converters
• Class D audio amplifiers

Procurement Notes

Verify the specific suffix 'GCJ' corresponds to the HWSON8 package variant when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input logic levels match the specified 2.5 V, 3.3 V, or 5 V compatibility requirements. Validate thermal management strategies for the operating temperature range of -40°C to +125°C. Cross-reference datasheet revisions to ensure pinout and electrical characteristics remain unchanged.

Selection Notes

Select this component for designs requiring precise delay matching between high-side and low-side drivers. It is suitable for applications needing fast switching speeds with minimal cross-conduction risk. The integrated bootstrap diode simplifies circuit design for high-side driving. Consider the 120 V floating supply capability for medium-voltage applications. Evaluate the 4 A/5 A output currents against the target MOSFET gate charge requirements.
