UCC27325P

Gate Driver Overview

The UCC27325P is a dual high-speed low-side power MOSFET driver manufactured by Texas Instruments. It provides a peak output current of 4 A to drive capacitive loads efficiently. The device operates within a supply voltage range of 4.5 V to 15 V and features TTL/CMOS compatible inputs. Typical switching times include a rise time of 20 ns and a fall time of 15 ns, with propagation delays of 25 ns for input falling edges and 35 ns for rising edges. It is housed in an 8-pin PDIP package.

Gate Driver Feature Summary

• Utilizes TrueDrive output architecture combining bipolar and CMOS transistors for efficient current sourcing and sinking at low voltages
• Designed to minimize shoot-through current during switching transitions
• Features industry-standard pinout for easy replacement

Gate Driver Applications

• Driving power MOSFETs in low-side configurations
• High-speed switching applications requiring large peak currents
• Industrial motor control systems

Gate Driver Procurement Notes

Verify the specific suffix 'P' corresponds to the PDIP-8 through-hole package when ordering. Confirm that the required logic configuration matches the non-inverting or inverting variant available within the UCC2732x series, as standard part numbers may denote specific polarity options. Ensure the application environment remains within the specified operating temperature range.

Gate Driver Selection Notes

Select this component for applications demanding high peak current capability to overcome Miller plateau effects during MOSFET switching. It is suitable for designs requiring fast transition times and compatibility with standard digital logic levels. Consider thermal management requirements if driving heavy capacitive loads continuously.

Gate Driver Part Context

This device belongs to the UCC2732x and UCC3732x family of high-speed dual MOSFET drivers. These components are designed to provide robust gate drive performance for power switches. The family offers various logic options and packaging types, including SOIC and PowerPAD MSOP, to suit different board space and thermal constraints.

Gate Driver Replacement Considerations

Direct substitutes within the same family include UCC27324P and UCC27326P, which share similar electrical characteristics but differ in input logic polarity (inverting vs. non-inverting). Cross-family replacements like UCC37325 require verification of package and logic compatibility.
