UCC37324DGN

Gate Driver Overview

The UCC37324DGN is a dual low-side power MOSFET driver manufactured by Texas Instruments, housed in an 8-pin MSOP PowerPAD package. It features two independent non-inverting outputs capable of delivering a peak output current of 4 A. The device operates within a supply voltage range of 4 V to 15 V and supports CMOS logic inputs with defined thresholds of 1 V for low-level input and 2 V for high-level input. Typical switching performance includes rise and fall times of 23 ns. The component functions within an operating temperature range of 0°C to +70°C.

Gate Driver Feature Summary

• Dual channel configuration providing independent control for two low-side MOSFETs
• High-speed switching capability with hysteretic logic design for improved noise immunity
• Integrated PowerPAD thermal pad structure to enhance heat dissipation efficiency

Gate Driver Applications

• Synchronous rectification circuits in DC-DC converters
• Motor drive systems requiring low-side switching control
• Power supply management units utilizing MOSFET gate driving

Gate Driver Procurement Notes

Verify the specific suffix 'DGN' to confirm the MSOP-PowerPAD package variant, as other suffixes indicate different form factors like SOIC or tape-and-reel quantities. Ensure the procurement source provides official datasheets confirming the non-inverting logic configuration and 4 A peak current rating. Cross-reference the manufacturer part number against authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required for specific manufacturing standards.

Gate Driver Selection Notes

Select this component when a dual-channel low-side driver with moderate speed (23 ns) and high current capability (4 A) is required. The MSOP PowerPAD package is suitable for applications needing compact surface-mount solutions with improved thermal performance compared to standard packages. Consider the non-inverting logic requirement; if inverting logic is needed, the UCC37323 series should be evaluated instead. Verify that the system's supply voltage remains within the 4 V to 15 V operational window.

Gate Driver Part Context

The UCC37324DGN belongs to the UCC3732x family of high-speed power MOSFET drivers from Texas Instruments. This family includes variants such as the UCC37323 (inverting), UCC37324 (non-inverting), and UCC37325 (high-side). The DGN suffix specifically denotes the 8-lead MSOP PowerPAD package, distinguishing it from the SOIC versions (e.g., UCC37324D) and through-hole PDIP options (UCC37324P).

Gate Driver Replacement Considerations

Public confirmed substitute part numbers include UCC37324DG4 and UCC37324DGNR.
