UCC37325DR

Overview

The UCC37325DR is a dual high-speed low-side power MOSFET driver from Texas Instruments, designed for applications requiring rapid switching. It features 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 with independent inputs and outputs, providing both inverting and non-inverting signal paths. Typical propagation delay is 25 ns, with rise and fall times around 20 ns under standard loading conditions. It is housed in an 8-pin SOIC package.

Feature Summary

• Dual-channel architecture with independent inverting and non-inverting outputs
• High peak drive capability of 4 A for efficient capacitive load charging
• Hysteretic logic design ensures stable operation across varying input levels
• CMOS-compatible input interface for direct connection to logic controllers

Applications

• Switching mode power supplies (SMPS)
• DC/DC converter topologies
• Motor controller circuits
• Line driver interfaces

Procurement Notes

Verify the specific suffix 'DR' against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration. Ensure that the ordering information matches the exact part number variant required for the intended production volume and handling specifications.

Selection Notes

Select this component when a dual low-side driver with asymmetric output polarity is required. The 4 A peak current rating supports moderate capacitive loads without external buffering. Consider thermal dissipation requirements relative to the SOIC-8 package limitations for continuous duty cycles.

Part Context

This device belongs to the UCC3732x series of high-speed gate drivers. It shares functional similarities with the UCC2732x family but offers distinct pinout or feature variations defined by the manufacturer. The series targets general-purpose power management and motor control applications.

Replacement Considerations

The UCC37325DGN serves as a pin-compatible alternative in an MSOP package. Cross-reference electrical parameters such as propagation delay and quiescent current to ensure compatibility with existing circuit designs.
