UCC37325DGNRG4

Overview

The UCC37325DGNRG4 is a dual low-side power MOSFET driver manufactured by Texas Instruments. It features two independent drivers with a peak output current of 4 A and operates within a supply voltage range of 4 V to 15 V. The device utilizes hysteretic logic for high-speed switching, achieving rise and fall times of 23 ns. It is housed in an 8-pin MSOP-PowerPad package designed for surface mount installation. The component supports both inverting and non-inverting outputs and functions at temperatures between 0°C and +70°C.

Feature Summary

• Dual channel configuration providing independent control for two low-side MOSFETs
• Hysteretic logic architecture enabling high-speed signal processing
• Integrated PowerPad thermal management for efficient heat dissipation

Applications

• Power MOSFET gate driving in motor control systems
• High-speed switching applications requiring low-side drive
• DC-DC converter topologies utilizing low-side switches

Procurement Notes

Verify the specific suffix RG4 indicates RoHS compliance and green material status as per manufacturer specifications. Confirm the MSOP-PowerPad-8 package variant matches the required PCB footprint. Ensure the operating temperature range aligns with the intended application environment constraints before finalizing procurement orders.

Selection Notes

Select this component when dual low-side drive capability with 4 A peak current is required. The hysteretic logic offers faster response compared to standard CMOS inputs. Consider the thermal performance of the PowerPad package for high-current applications. Verify that the 4 V to 15 V supply range suits the system's available voltage rails.

Part Context

This part belongs to the UCC3732x series of high-speed MOSFET drivers from Texas Instruments. It shares the same package and basic functionality as the UCC37325DGN but includes specific manufacturing and compliance markings indicated by the RG4 suffix. It serves as a low-side driver alternative to high-side or half-bridge variants within the broader driver portfolio.

Replacement Considerations

The UCC37325DGN is a direct pin-compatible replacement without the RG4 suffix. Other family members like UCC37323DGN offer similar electrical characteristics but may differ in output configuration or packaging details.
