UCC27512DRSR

Gate Driver Overview

The UCC27512DRSR is a single-channel, high-speed, low-side gate driver manufactured by Texas Instruments. It features hysteretic logic for robust operation and supports both inverting and non-inverting input configurations. The device delivers peak output currents of 4 A source and 8 A sink, enabling efficient switching of power MOSFETs and IGBTs. Operating within a supply voltage range of 4.5 V to 18 V, it exhibits typical rise and fall times of 9 ns and 7 ns, respectively. Designed for surface-mount installation, it is housed in a compact 6-WSON package with exposed thermal pad.

Gate Driver Feature Summary

• Integrates hysteretic logic to ensure stable switching performance under varying load conditions.
• Provides dual input configuration options supporting both inverting and non-inverting signal processing.
• Delivers asymmetric peak drive current capability optimized for rapid power switch transitions.

Gate Driver Applications

• Driving N-channel power MOSFETs in low-side switching topologies
• Gate driving IGBT modules in industrial motor control systems
• High-frequency power conversion circuits requiring fast switching speeds

Gate Driver Procurement Notes

Verify the specific suffix DRSR corresponds to the WSON-6 package and tape-and-reel packaging format. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to integration into assembly processes. Ensure the ordering part number matches the required input logic configuration and output current specifications for the target application design.

Gate Driver Selection Notes

Select this component when a single-channel low-side driver with asymmetric drive strength is required. The hysteretic logic feature distinguishes it from standard CMOS drivers, offering improved noise immunity. Consider the 6-WSON package constraints for thermal management and PCB layout space. Verify that the 4.5 V minimum supply voltage aligns with the system's available rail voltages.

Gate Driver Part Context

This device belongs to the UCC2751x family of high-speed gate drivers from Texas Instruments. It shares architectural similarities with other members like the UCC27511 but differs in pinout and specific electrical characteristics. The family is designed for general-purpose power switching applications where speed and reliability are critical parameters for system efficiency.

Gate Driver Replacement Considerations

Public confirmed substitute part numbers include UCC27511DRLR and UCC27511DRSR. Verify pin compatibility and electrical parameter alignment before substitution. The UCC27512-EP variant offers enhanced product specifications for high-reliability environments.
