UCC27526DSDT

Gate Driver Overview

The UCC27526DSDT is a dual low-side power MOSFET gate driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 5 A. The device features hysteretic logic for flexible input compatibility with CMOS and TTL standards. It provides propagation delays of 13 ns, with rise and fall times of 7 ns each. The component is housed in an 8-pin WSON package and supports surface mount installation. It functions reliably across an extended temperature range from -40°C to +140°C.

Gate Driver Feature Summary

• Dual-channel architecture providing independent control for two low-side power switches
• Hysteretic logic design ensures stable operation with flexible input threshold requirements
• High-speed switching capability with symmetric 7 ns rise and fall times
• Robust thermal performance supporting continuous operation up to 140°C junction temperature

Gate Driver Applications

• Power factor correction circuits requiring precise low-side switching
• DC-DC converter topologies utilizing synchronous rectification
• Motor drive systems controlling low-side IGBT or MOSFET stages
• Inverter bridges needing isolated or non-isolated gate drive signals

Gate Driver Procurement Notes

Verify the specific suffix DSDT indicates the tape-and-reel packaging format distinct from cut-tape variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the exact part number against the latest datasheet revision to validate pinout and electrical specifications.

Gate Driver Selection Notes

Select this component when dual low-side driving is required without high-side complexity. The hysteretic logic simplifies interface design compared to standard threshold drivers. Consider the 5 A peak current capability for moderate-power applications. Evaluate the WSON-8 footprint constraints against available PCB real estate. Compare propagation delay characteristics against system timing requirements.

Gate Driver Part Context

This device belongs to the UCC2752x family of high-speed gate drivers. It shares core electrical specifications with the UCC27526DSDR variant, differing primarily in packaging quantity and reel configuration. The series targets efficient power conversion applications where switching speed and drive strength are critical. It complements higher-voltage gate driver offerings in the Texas Instruments portfolio.

Gate Driver Replacement Considerations

The UCC27526DSDR serves as a direct functional substitute with identical electrical characteristics. Verify that the alternative packaging format meets assembly line requirements. No changes in function or pinout are expected between these variants.
