UCC27323DR

Gate Driver Overview

The UCC27323DR is a dual high-speed low-side MOSFET gate driver manufactured by Texas Instruments. It provides a peak output current of 4 A with a supply voltage range of 4 V to 15 V. The device features inverting logic and utilizes an SOIC-8 package. Typical switching times include a 20 ns rise time and a 15 ns fall time. Operating temperatures span from -40°C to +125°C, with a quiescent current of 450 µA.

Gate Driver Feature Summary

• Dual inverting outputs for independent low-side control
• Hysteretic logic input for noise immunity
• High peak current drive capability for fast switching

Gate Driver Applications

• Low-side MOSFET switching in power converters
• Industrial motor control systems
• Inverter bridge circuits

Gate Driver Procurement Notes

Verify the specific suffix 'DR' indicates tape-and-reel packaging distinct from tube variants. Confirm RoHS compliance status through official documentation as specifications may vary by production batch. Ensure the component matches the required inverting logic configuration for the target circuit design.

Gate Driver Selection Notes

Select this component when dual low-side driving is required within a compact SOIC-8 footprint. The 4 A peak current supports standard MOSFET loads efficiently. Verify that the inverting logic aligns with the system's control signal polarity requirements before integration.

Gate Driver Part Context

This part belongs to the UCC2732x series of high-speed MOSFET drivers. It shares architectural similarities with the UCC27323D but differs in packaging format. The series emphasizes thermal performance and switching speed for power management applications.

Gate Driver Replacement Considerations

The UCC27323DG4 is a verified lead-free variant of the same functional device. Cross-reference pinouts and electrical parameters to ensure compatibility during substitution.
