UCC27525DSDT

Gate Driver Overview

The UCC27525DSDT is a dual-channel, high-speed low-side gate driver from Texas Instruments. It delivers peak output currents of 5A source and 5A sink to drive power MOSFETs and IGBTs. The device operates on a single supply voltage ranging from 4.5V to 18V. It features inverting and non-inverting logic inputs with typical propagation delays of 13ns. Rise and fall times are typically 7ns and 6ns respectively. The component functions within an operating temperature range of -40°C to +140°C and is housed in a WSON-8 package.

Gate Driver Feature Summary

• Provides independent enable pins for each channel to control driver operation
• Features matched internal propagation delays between channels for critical timing applications
• Includes internal pull-up and pull-down resistors to maintain low output states when inputs are floating

Gate Driver Applications

• Synchronous rectifiers requiring precise dual-gate drive timing
• Driving parallel power switches using a single input signal
• General-purpose low-side switching for MOSFET and IGBT power stages

Gate Driver Procurement Notes

Verify the specific suffix DSDT corresponds to the WSON-8 tape-and-reel packaging configuration. Confirm that the order quantity aligns with the manufacturer's standard reel size requirements. Ensure compatibility with surface-mount assembly processes suitable for the specified package type. Check for RoHS compliance documentation if required by your manufacturing standards.

Gate Driver Selection Notes

Select this component when dual-channel low-side driving with independent enable controls is necessary. It is suitable for applications demanding rail-to-rail drive capability and minimal shoot-through current. Consider this part for designs requiring flexible input logic configurations with both inverting and non-inverting options available in a single package.

Gate Driver Part Context

This device belongs to the UCC2752x series of dual high-speed low-side gate drivers. The series is designed to effectively drive capacitive loads with high peak currents. Other members include variants with different input logic combinations such as dual inverting or dual non-inverting configurations.

Gate Driver Replacement Considerations

UCC27525DSDR is a compatible alternative within the same series offering identical electrical specifications but potentially differing in reel packaging quantities.
